Top 7 Examples of .NET Applications

Phenomenal results - that's what one of the companies experienced after switching to .NET. Explore 7 most interesting examples of .NET applications along with the curious details about apps and results they brought.


Examples of .NET applications

These 7 companies used .NET in their projects:

  • Forza Horizon
  • Academy of Motion Picture Arts and Sciences
  • BBC Good Food
  • Allegiance Consulting
  • American Cancer Society

Read on to learn more about these apps along with successes and problems .NET generated in the projects.


Are you thinking of switching to .Net to build your applications? If yes, this article covers examples of .Net applications and why the developers chose the toolset. 

But first, let's see why you should consider the switch.

The mobile app market is projected to generate revenues of $935 billion in 2023. This comes as no surprise as applications have become a key part of people's personal and professional lives. 

There are approximately 3.8 billion smartphone users across the globe. And the average smartphone owner uses ten apps daily. 

As a software engineer, the market offers tremendous opportunities. However, you need to have the right tools to build apps. 

This is why many developers are now turning to .NET. It's a powerful, feature-packed toolset for building desktop and mobile apps, web apps, and gaming and IoT solutions. 

GoDaddy is a US-based company that helps businesses succeed by offering industry-leading domain registration and hosting services. Its focus is on small independent businesses for which it provides a dedicated cloud platform.

According to GoDaddy, it has over 6,000 employees and 17 million-plus clients across the globe. Along with being robust and having great features, it is highly secure and intuitive, enhancing customer experience. 

Why Did They Choose .NET?

As a hosting provider for small businesses, GoDaddy is committed to offering highly efficient and scalable solutions. By using .NET Core with C#, GoDaddy is able to improve production performance, develop more solutions in a shorter period, and scale better. 

Beyond this, GoDaddy enjoys greater freedom to capitalize on new infrastructure technologies on Linux, such as Docker and Kubernetes. 

Here's what GoDaddy's Principal Software Architect, Jeremiah Gowdy has to say about .Net.

"I was able to quickly remediate 99 percent of the incompatibilities just by shifting from older APIs to the more preferred APIs that we use today."

With over a century under its belt, UPS is one of the largest package delivery companies. It handles over 19 million deliveries to over 220 countries and territories daily. 

To ensure it continues to deliver exemplary delivery services to its ever-increasing customer base, UPS invests $1 billion annually in innovative technologies. The UPS Mobile app is one such solution. It allows customers to manage, track, nickname shipments, estimate costs and delivery times, find UPS service locations, and create shipping labels on the go. 

Why Did UPS Choose .NET?

UPS had to deal with a fragmented web development process, as with most companies. As a result, pushing new features across multiple device platforms required a lot of work and time. 

However, after consolidating its codebase with a combination of tools, including .NET, UPS now enjoys faster time to market, enhanced efficiency, etc. 

Here's what Katie Duffy, the Application Architect of UPS, has to say:

"Conversation as a platform is the future, so it's great that we're already offering it to our customers using the Bot Framework and Azure. Even though we're just getting started with our bot, we believe we are the first in the shipping industry to offer this type of technology on social media."

3. Forza Horizon

Among the best examples of .NET applications is Forza Horizon, a racing video game developed by Playground Games and Turn 10 Studios. The game is published by Xbox Game Studios and was first released in 2012.

With each new release, it gains more and more fans. For example, when Forza Horizon 5 was released, it had over 10 million concurrent players, marking the biggest week for an Xbox Game Studios release. 

Why Forza Horizon Uses .NET

As Forza Horizon continues to gain popularity and grow in size, the infrastructure needed to support it also increases. Also, players expect top-notch graphics, efficient gameplay, and improvements with each release. 

While this was a challenge early on, things are much easier since Forza Horizon moved its code based on the .NET Framework and Internet Information Services (IIS) to Azure Cloud Services (Classic).  

Now Forza Horizon enjoys an ultra-low latency, accelerated networking, and a lower CPU utilization thanks to a high-performance path that reduces jitter. 

Tyler Hennessy, the Principal Software Engineering Lead of Turn 10 Studios, commented as follows:

"At launch, when we had over 1 million concurrent users, all 17 services autoscaled and end-to-end latency never went above 100 milliseconds."

4. Academy of Motion Picture Arts and Sciences

The Academy of Motion Picture Arts and Sciences sets the bar when it comes to the movie world. One of its most popular features is the Oscars, an annual awards ceremony that celebrates the best performances.

Why the Academy of Motion Pictures and Arts Uses .NET

In the past, most of the Academy of Motion Picture Arts and Sciences' data existed in isolated on-premise databases and even on paper. As you can imagine, that's highly inefficient.

After migrating to the cloud, it now enjoys streamlined IT development and can serve the members better. This comes via responsive online experiences across different types of devices.  

One of the reasons the Academy chose to use Azure is because Microsoft is best placed to understand .NET and SQL. 

Here's what Bev Kite, the Chief Information Officer of the Academy, said about the transitions:

"Azure gave us built-in scalability and high availability, which allowed us to take more risks. We were able to go from streaming just a few award categories to streaming all award categories, including Best Picture. Even better, because Azure is subscription-based, we no longer need to pay for more scalability before we need it."

5. BBC Good Food

BBC Good Food is a product of the BBC Worldwide brand. So as you can imagine, it's a provider of food-related content online. The content touches on recipes, health, family, and travel. 

While everyone loves a good meal, getting the time to plan for it or come up with a delicious recipe is rarely available. BBC Good Food helps with this as it provides all the necessary information that's accessible remotely.

Why BBC Good Food Uses .NET

With over 10,000 recipes and millions of visitors monthly, BBC Good Food knows that it can remain so popular by improving customer engagement and loyalty. 

By using .NET, the company was able to create a mobile-first solution that enhances the customer experience by offering personalized recommendations. 

Matt Pickering, the Managing Director of NV Interactive, best captures the intention and results:

"BBC Good Food wanted to move fast, and the only way to do that was to take a single platform approach. We knew Visual Studio Tools for Xamarin was the best choice for fast development while still helping ensure native-quality apps."

6. Allegiance Consulting

Allegiance Consulting (Pty) Ltd is a fintech company that provides complex financial planning systems based in South Africa. It started operations in 1999 with legal and business consultants. 

After years of continued growth, it now features UX specialists, quants, and talented developers to build advanced financial planning solutions. 

Why Allegiance Consulting Chose .NET

As the demand for financial planning systems increased, there was a need to accelerate the development process. In addition to the speed, it was important for solutions to be scalable and highly secure. 

Another reason the company turned to .NET is the need to reduce time to market and reach international markets with ideal solutions. 

The CEO of Allegiance Consulting, Kobus Barnard, explains:

"Our next steps? Automate our infrastructure layer that is hosted on Azure. We want to ensure that we can spin up new environments without human interaction, so we can deploy continuously using Azure DevOps as our base pipeline layer. We are also currently at IoT devices on the edge for enhanced security using FIDO keys and AI to further enhance the user experience on our SaaS applications."

7. American Cancer Society

On its mission to rid the world of cancer, the American Cancer Society greatly relies on volunteers. The organization uses mobile apps to keep them informed and actively support the cause.

Why the American Cancer Society Chose .NET

Due to high database costs, slow development, and disorganized processes, the society's IT team decided to adopt Microsoft Azure DevOps along with .NET Core as an open-source technology. 

As a result, data storage deployment costs have reduced significantly while funds raised have increased.

Ben Kaplan, the Senior Director of Digital Products at the American Cancer Society, puts it best:

"Results … have been simply phenomenal. The first year, we did 86 percent more revenue year over year. Last year, we did over 55 percent more revenue."

Some of the frequently asked questions about the examples of .NET applications include:

1. What are the types of .NET applications?

You can use .NET to create different types of apps, including console, Windows GUI, Windows Presentation Foundation, Windows services, ASP.NET, workflow-enabled, and service-oriented apps.

What is .NET used for? 9 Examples of .NET Applications

Are you thinking about choosing the .NET framework and its tools for your new development project but aren’t sure if it would be a good choice? <br> We’ve prepared nine different examples of projects that were either built from scratch or modernized using the powers of .NET to show you just how versatile the framework can be.


Over the past few years, .NET has firmly held the top slot in the Stack Overflow survey in the “Other frameworks” category. For example, in the  Stack Overflow 2022 survey , almost 35% of professional developers picked .NET as their most often used framework. Considering how  flexible, reliable, but also developer-friendly  the framework is, this popularity shouldn’t be anything surprising.

Let’s take a look at a few companies that have used .NET in their projects with success.

Stack Overflow

Our first example will be Stack Overflow, a community-based Q&A website for developers.  The Stack Overflow team has used the .NET framework to power its website from the very beginning.  In 2018, though, they announced that they were  migrating their system architecture to  .NET Core  in order to solve some of the problems plaguing the older technology.

What has Stack Overflow gained from using .NET applications?

Among the major changes following the migration is that their  infrastructure has become much faster . Thanks to this, the Stack Overflow team can now build applications faster, but it also takes less time for users to find the information they need.

But what has really made the difference for them is that now they can  build and run applications on different operating systems   and deploy them via the Azure cloud platform .

Nick Craver

Architecture Lead at Stack Overflow

With .NET Core 3.0, we can build an app and then run it on our Windows developers’ machines, design computers on Mac, and the enterprise cloud in Linux. We can build the application in one way, and that’s tremendous.

Another thing .NET core helped them with is by  making Stack Overflow applications more modular . With the modules, the Stack Overflow team can host different parts of an application in separate places and also experiment with Kubernetes and Docker.

.NET Core also made testing applications easier for the development team.  Now they can test a method, end-to-end, or server with ease – something they struggled with on the older version of the .NET framework.

With .Net Core, I’m not fighting all of the meta of building software. We can actually just go and build the software.


UPS is one of the largest package delivery companies Worldwide, handling over 24 million deliveries daily to over 220 countries and territories.  To improve customer service and increase its IT staff efficiency, UPS decided to run two projects:

  • Building a faster, consolidated version of  UPS Mobile  so the app would work smoothly on different devices, reducing the amount of work developers needed to maintain the app code.
  • Designing a  UPS Bot  that would let customers find information about shipments, rates, and UPS locations via text or voice commands.

Both of those projects were run on .NET, Azure, and Visual Studio Tools for Xamarin.

What has UPS gained from using .NET applications?

With the new version of their mobile app,  the amount of code that UPS developers need to maintain has dropped by half . What’s more, developers now also need  only a few weeks  at most to implement new features to their apps  compared to months previously.

Also, UPS’s new app has significantly  improved the user experience  – customers can use the application on multiple devices, both iOS and Android.

The UPS Bot, meanwhile (built with the .NET framework),  made the support team’s job much easier  as it handles the majority of simple and repetitive questions for them. Customers can also talk with the chatbot either by using the text field or by giving it voice commands, whichever is more convenient for them.

UPS Architect

Conversation as a platform is the future, so it’s great that we’re already offering it to our customers using the Bot Framework and Azure. Even though we’re just getting started with our bot, we believe we are the first in the shipping industry to offer this type of technology on social media.

Forza Horizon 5

What about games in which users expect top-notch graphics, smooth gameplay, and outstanding performance? Would the .NET framework and its applications also be helpful here? Forza Horizon 5’s success proves just that –  the .NET framework can also be an excellent choice for video games.

Forza Horizon is a racing game developed by Playground Games and Turn 10 Studios, released in 2012. The latest edition, Forza Horizon 5, was released in November 2021 and immediately became a massive hit. In the very first week, the game had  10 million concurrent players  – a new Xbox and Game Pass record.

However, the game’s growing popularity started becoming a problem for the developers as they struggled to scale up the infrastructure. That’s why they decided to migrate their entire code base to Azure Cloud Services with virtual machines and eventually to Azure Kubernetes.

What has Forza Tech gained from using .NET applications?

Thanks to the migration, the studio can take advantage of ultra-low latency, accelerated networking, and lower CPU utilization for better performance.  Moreover, with autoscaling Azure Kubernetes service clusters, the game can automatically adapt to changing demands.

But what made the ForzaTech developers especially happy is that  Kubernetes enabled them to run stress testing much more efficiently . Previously, they needed at least half an hour to swap out old images on the VMs and prepare them for load. With Azure Kubernetes, this process takes seconds, allowing the developers to make changes in a flash.

Daniel Adent

General Manager of ForzaTech

With our compute, storage, and data stacks all on Azure, our engineering teams can now spend more time building new experiences for our players rather than managing our infrastructure.

Academy of Motion Picture Arts and Sciences


The Academy of Motion Picture Arts and Sciences is best known for its annual awards ceremony, the Oscars®. As hard as it might be to believe, however,  for years the vast majority of tasks related to picking nominees and category winners were done offline and most of their data was either held in on-premise databases or paper documents .

In 2014, the Academy decided it was high time to  modernize its website  and also  design a new mobile app  for Academy members. So, after analyzing their options, the Academy decided to move its infrastructure to the Azure Cloud platform.

What has the Academy gained from using .NET applications?

The Academy’s .NET Framework applications now run in Azure App Service. Thanks to its deployment slots,  they no longer need to put applications on downtime  whenever they need to add new content to the member portal. Moreover, Academy members can now watch movies (even from the “Best Picture”) category and cast their votes across various devices.

The data that used to reside in on-premises SQL Server databases, meanwhile, now is stored in Azure SQL, which shares its code base and SQL query language with SQL Server.  This enabled the Academy’s team to quickly and safely migrate the entire database to the cloud.

But what the academy points out is that  the migration also helped them move to work remotely  during the Covid-19 pandemic.

Chief Information Officer

Everything we do now is through the cloud, including ongoing software development. Azure helped us keep going during Covid-19. If we had still been on-premises, it would have been more difficult. We’ve managed to increase our ability to respond to member needs because we’re a lot more agile and flexible now.

Allegiance Consulting

Another company that also mentions Covid-19 as the main driver behind the decision to move to the cloud is Allegiance Consulting, a South African  fintech company  specializing in complex financial planning systems.

The forced move to remote work brought three challenges for them:

  • Staying in touch  with their employees and clients during lockdown times
  • Developing applications on a  highly secure  but also  flexible infrastructure
  • Reassuring their anxious clients that the consulting company was working as usual

The Azure cloud service turned out to be the perfect solution to all those problems.

What has Allegiance Consulting gained from using .NET applications?

One of the things they did to put their clients at ease was  to   create an application using the Blazor web framework . The application worked as a diagnostic tool that also gave users tips on how to deal with a health crisis financially and what they should do to stay safe. That way, the company could stay in touch with its clients during the lockdown periods.

Kobus Barnard

CEO at Allegiance Consulting

We deployed the application on Microsoft Azure, which gave us the scalability and security needed for an enterprise-level application in the financial services sector.

The company also moved its financial advice platform, Avalon, from a private cloud (which they have been using for ten years) to Azure. The benefits of the migrations were visible almost immediately –  significant savings on infrastructure costs and the ability to scale applications up or down whenever they needed .

GE Digital FlightPulse


GE Digital is a global leader in airline manufacturing, avionics, electrical power, and mechanical systems for aircraft. To make the skies safer and pilots more confident, GE Digital wanted to  build an application through which pilots could easily access data coming from aircraft systems and sensors .

Building such a complex solution the traditional way could take years, though. So instead, GE Digital built and deployed the application using Microsoft developer tools, GitHub, and Microsoft Azure.

What has GE Digital gained from using .NET applications?

GE built the backend APIs for FlightPulse using ASP .NET Core and then used Blazor to build its Config Console App. For the code editor, meanwhile, they used Microsoft Visual Studio Code and the platform’s extensions, such as Live Share for real-time coediting and IntelliCode for AI code completion.

Additionally, the GE team uses Azure Key Vault, Azure SQL Database, and Azure Storage to store airline data. The results?

Principal Architect at GE

We were able to build the app faster and work more efficiently given the componentization that we were able to use out of the box with Blazor. And it worked a lot more seamlessly than some of the stuff we’d done previously in Angular.


Geocaching is a game of hide-and-seek where players leave boxes in specific places and other players try to find them.

Initially, geocaching.com was meant just as a simple website through which players could find geocaches in their area. As mobile devices with in-built GPS became widespread though, the company started to grow rapidly as well –  going from serving thousands to millions of players .  Thus, the company needed to scale up its web application quickly to meet the growing demand.

.NET provided a perfect solution to their needs.

What has geocaching.com gained from using .NET applications?

Now,  their entire backend is built with .NET web APIs . By using the .NET framework, they can create web APIs that can  smoothly handle millions of players all over the world, 24/7 . The geocaching database also  stores over a billion geocache logs  now.

Director of Engineering

.NET has been the cornerstone for us because it’s been helping us grow and scale along with our customer base. It’s reliable. It does what I want it to do. It’s secure, and everyone knows how to use it. It performs. It’s my favorite platform.

The Postage


The Postage is a startup website that allows people to create and store information that can be used in the future by their families, such as:

  • Last will and funeral preferences
  • Financial information
  • Medical records
  • Online passwords
  • Other legal documents

Before their idea became a real product, however, they needed to secure funding for the project. And for this, the startup needed to create a working product demo first.

Since they knew they would be storing  plenty of sensitive information, making the application as secure as possible was a priority . What’s more, the ready application also needed to be easy to use, scalable, and offered high availability as well. Microsoft .NET had everything they needed for the task.

What has The Postage gained from using .NET applications?

To bring this idea to life, Ken Myers (now the company’s Chief Technology Officer) started analyzing the platforms they could work on and ultimately decided to use Microsoft Azure.

Chief Technology Office

I knew we wanted to use .NET, and Azure is the best cloud for NET. What’s more, with .NET, we would get access to Blazor and Xamarin, which let us use C# across the entire application stack, from the front end to the back end to mobile. That approach has proven to be very effective in terms of both speed and cost.

By using Blazor, their small development team could work both on the front end and the back end of the solution without having to hire two separate groups for the development. The beta version of the application went live in June 2020, and the complete application was released three months later.

Emily Cisek

Chief Executive Officer

We’re seeing strong growth in terms of site traffic, account subscriptions, and general interest in the overall platform. And those people who do subscribe are actively uploading documents, adding their accounts and passwords, and saving messages for loved ones. It’s all coming together as we had hoped – we’re hearing stories about how it’s helping people change how they plan for the future, which is exactly what we set out to achieve.

Siemens Healthineers

Our last example will be a company from the healthcare sector – Siemens Healthineers. One of their main products, Digital Ecosystem, is intended to help healthcare providers offer better care to patients by giving the providers better quality insights derived from healthcare data.

Yet, as healthcare companies must comply with several data security and privacy laws, they must be extra careful when migrating data to the cloud.  That’s why Siemens Healthineers thoroughly researched their options to ensure its clients would be comfortable with having their private data stored in the cloud.

Ultimately, they selected Microsoft Azure, since the platform has many security certifications that helped the company reassure their customers that cloud storage is as secure as any other on-premises data center.

What has Siemens Healthineers gained from using .NET applications?

For deploying and managing their applications, Siemens Healthineers uses Azure Kubernetes Service (AKS). Using this service,  developers can quickly and easily work with their applications  without taking them offline for maintenance or upgrading, reducing downtime significantly.

Their development team also appreciates that  they can comfortably scale up  the Kubernetes environment  and scale it back down again when they don’t need the extra computing power . Siemens Healthineers also uses other Azure services for their applications, such as the Azure Cosmos database.

Thomas Gossler

Lead Architect

Azure Cosmos DB is an amazing technology. The biggest benefit for us is that we can have one database for anonymous data that is replicated worldwide into all regions that are relevant to us.

As you can see,  .NET development  can be tailored to virtually any industry or project.  Healthcare, gaming, or maybe fintech? Whatever project you have in mind, the .NET framework and the applications running on it can give you outstanding performance and customer experience.

To enjoy all the benefits .NET can bring to your project though, you’ll need a reliable partner like our talented .NET developers at Inwedo. So how about  meeting our team  for a short chat, so we could show you how you can bring the full potential of .NET?

24 Sample Web Application for .NET Clients

This chapter provides step-by-step instructions to create a simple Windows ASP.NET Web application that uses the Coherence for .NET library.

General Instructions

Developing and configuring a Windows ASP.NET web application that uses Coherence for .NET requires six basic steps:

Create an ASP.NET Project

Add a reference to the coherence for .net library, configure the web.config file, create coherence for .net configuration files, create the web form.

Implement the Web Application .

The following sections describe each of these steps in detail.

To create a new ASP.NET web application, follow these steps:

Choose File->New->Web site in Visual Studio 2005.

Under the " Templates ", select " ASP.NET Web Site ".

Select the language that you are most familiar with.

Select the location (type and full path) where you want to store your application.

Click the OK button to generate a new solution and empty ASP.NET application.

To use the Coherence for .NET library in your .NET application, you first need to add a reference to the Coherence.dll library:

In your project go to Project->Add Reference ... or right click References in the Solution Explorer and choose Add Reference... .

In the Add Reference window that appears, choose the Browse tab and find the Coherence.dll library on your file system.

Figure 24-1 Coherence.dll File in the Add Reference Window

Description of Figure 24-1 follows

To correctly configure the Coherence for .NET library, you must configure the Web.config XML file with the appropriate file names for each configuration file used by the Coherence for .NET library. Example 24-2 illustrates a valid Web.config configuration file:

Example 24-1 Sample Web.config Configuration File

In the <configSections> you must specify a class that handles access to the Coherence for .NET configuration section.

Elements within the Coherence for .NET configuration section are:

cache-factory-config —contains the path to a configuration descriptor used by the CacheFactory to configure the ( IConfigurableCacheFactory and Logger ) used by the CacheFactory .

cache-config —contains the path to a cache configuration descriptor which contains the cache configuration described earlier (see "Configuring Coherence*Extend on the Client" ). This cache configuration descriptor is used by the DefaultConfigurableCacheFactory .

pof-config —contains the path to a configuration descriptor used by the ConfigurablePofContext to register custom types used by the application.

Example 24-2 illustrates a sample coherence.xml configuration file:

Example 24-2 Sample coherence.xml Configuration File

Example 24-3 illustrates a sample cache-config.xml configuration file:

Example 24-3 Sample cache-config.xml Configuration File

Example 24-4 illustrates a sample pof-config.xml configuration file:

Example 24-4 Sample pof-config.xml Configuration File

Having creating these configuration files, everything is now in place to connect to a Coherence cluster and perform all operations supported by Coherence for .NET.

Switch to the Design tab for the Default.aspx page and from the Toolbox pane add the appropriate controls by dragging and dropping them on the page. You will need TextBox controls for the Name , Street , City , State , and Zip fields and corresponding label controls for each. This is illustrated in Figure 24-2 .

Figure 24-2 Adding Controls for the .aspx Page

Description of Figure 24-2 follows

After placing them on the page, you should change the ID and Text property for each control. As we won't be using labels in the code, you can leave their ID property values as generated, and just put appropriate labels in the Text property. You should name the ID and TextBox controls txtName , txtStreet , and so on. Add one button and rename its ID to btnSave and Text property to Save . This is illustrated in Figure 24-3 .

Figure 24-3 Changing IDs and Properties for Data Controls

Description of Figure 24-3 follows

Add one button and rename its ID to btnClear and Text property to Clear . This is illustrated in Figure 24-4

Figure 24-4 Adding a "Clear" Button to the Application

Description of Figure 24-4 follows

Add label and rename its ID to lblTotal . This label will be used to display the cache size. We have to add a RequiredFieldValidator from the Validation list of controls on the Toolbox pane and set its properties. This is illustrated in Figure 24-5 :

Figure 24-5 Adding a Field Validator and Setting its Properties

Description of Figure 24-5 follows

Please note that ControlToValidate property is set to the txtName control.

From the Data list of controls on the Toolbox pane, add a GridView control and an ObjectDataSource (named dsContact ). This is illustrated in Figure 24-6 .

Figure 24-6 Adding a GridView Control and an ObjectDataSource

Description of Figure 24-6 follows

Example 24-5 illustrates code for the GridView control source:

Example 24-5 Code for the GridView Data Control

Example 24-6 illustrates the ObjectDataSource code.

Example 24-6 ObjectDataSource Code

Now, let's add a Search pane by dragging and dropping a few labels, one DropDownList for a filter column, and a TextBox for filter criteria. This is illustrated in Figure 24-7 .

Figure 24-7 Search Pane

Description of Figure 24-7 follows

Implement the Web Application

Global.asax file.

In order to free up resources in the cluster when your ASP.NET application terminates, you need to call CacheFactory.Shutdown() within the Application_End event handler in Global.asax . Example 24-7 illustrates a Global.asax file and shows you how to do that, and also adds the call which redirects the user to an error page if an exception occurs.

Example 24-7 Redirecting a User to an Error Page

Business Object Definition

Example 24-8 illustrates the definition of the ContactInfo business object.

Example 24-8 Sample Business Object Definition File

Service Layer Implementation

Example 24-9 illustrates a class that will provide data to the data bind control. It must have a public GetData() method that will return an ICollection of data to the data bind control:

Example 24-9 Providing Data to the Data Bind Control

Code-behind the ASP.NET Page

Add an event handler that creates an inner object that provide data to the data bind control. This is illustrated in Example 24-10 .

Example 24-10 Event Handler to Provide Data to the Data Bind Control

The method illustrated in Example 24-11 refreshes the GridView displayed on the page, refreshes the total label lblTotal , and makes the btnClear and all buttons visible if there are objects in the cache:

Example 24-11 Method to Refresh the Grid View

The method illustrated in Example 24-12 handles page load events. If there is a getKey value in the Request , then the value mapped to the specified key in the cache is retrieved and the appropriate fields populated with its properties. If there is a removeKey value in the Request , the value mapped to the specified key is removed from the cache.

Example 24-12 Method to Handle Page Load Events

The helper method illustrated in Example 24-13 retrieves an ContactInfo object from the cache by a specified key:

Example 24-13 Retrieving a Business Object from the Cache through a Specified Key

Example 24-14 illustrates an the event handler for the btnSave button:

Example 24-14 Event Handler for a "Save" Button

Example 24-15 illustrates the event handler for the btnClear button:

Example 24-15 Event Handler for a :Clear" Button

Example 24-16 illustrates the event handler for the btnSearch button:

Example 24-16 Event Handler for a "Search" Button

Example 24-17 illustrates the event handler for the btnClearFilter button:

Example 24-17 Event Handler for a "Clear Filter" Button

Finally, you should add an ConnectionError.html page to the project with an appropriate error message in it.

Scripting on this page enhances content navigation, but does not change the content in any way.

Microsoft eShopOnWeb ASP.NET Core Reference Application

Sample ASP.NET Core reference application, powered by Microsoft, demonstrating a single-process (monolithic) application architecture and deployment model. If you're new to .NET development, read the Getting Started for Beginners guide.

A list of Frequently Asked Questions about this repository can be found here .

Overview Video

Steve "ardalis" Smith recorded a live stream providing an overview of the eShopOnWeb reference app in October 2020.

This reference application is meant to support the free .PDF download ebook: Architecting Modern Web Applications with ASP.NET Core and Azure , updated to ASP.NET Core 7.0 . Also available in ePub/mobi formats .

You can also read the book in online pages at the .NET docs here: https://docs.microsoft.com/dotnet/architecture/modern-web-apps-azure/

example of net application

The eShopOnWeb sample is related to the eShopOnContainers sample application which, in that case, focuses on a microservices/containers-based application architecture. However, eShopOnWeb is much simpler in regards to its current functionality and focuses on traditional Web Application Development with a single deployment.

The goal for this sample is to demonstrate some of the principles and patterns described in the eBook . It is not meant to be an eCommerce reference application, and as such it does not implement many features that would be obvious and/or essential to a real eCommerce application.

VERSIONS The main branch is currently running ASP.NET Core 7.0. Older versions are tagged.

Topics (eBook TOC)

  • Introduction
  • Characteristics of Modern Web Applications
  • Choosing Between Traditional Web Apps and SPAs
  • Architectural Principles
  • Common Web Application Architectures
  • Common Client Side Technologies
  • Developing ASP.NET Core MVC Apps
  • Working with Data in ASP.NET Core Apps
  • Testing ASP.NET Core MVC Apps
  • Development Process for Azure-Hosted ASP.NET Core Apps
  • Azure Hosting Recommendations for ASP.NET Core Web Apps

Running the sample using Azd template

The store's home page should look like this:

eShopOnWeb home page screenshot

The Azure Developer CLI ( azd ) is a developer-centric command-line interface (CLI) tool for creating Azure applications.

You need to install it before running and deploying with Azure Developer CLI.


And you can also install with package managers, like winget, choco, and brew. For more details, you can follow the documentation: https://aka.ms/azure-dev/install .

After logging in with the following command, you will be able to use the azd cli to quickly provision and deploy the application.

Then, execute the azd init command to initialize the environment.

Run azd up to provision all the resources to Azure and deploy the code to those resources.

According to the prompt, enter an env name , and select subscription and location , these are the necessary parameters when you create resources. Wait a moment for the resource deployment to complete, click the web endpoint and you will see the home page.

  • Considering security, we store its related data (id, password) in the Azure Key Vault when we create the database, and obtain it from the Key Vault when we use it. This is different from directly deploying applications locally.
  • The resource group name created in azure portal will be rg-{env name} .

You can also run the sample directly locally (See below).

Running the sample locally

Most of the site's functionality works with just the web application running. However, the site's Admin page relies on Blazor WebAssembly running in the browser, and it must communicate with the server using the site's PublicApi web application. You'll need to also run this project. You can configure Visual Studio to start multiple projects, or just go to the PublicApi folder in a terminal window and run dotnet run from there. After that from the Web folder you should run dotnet run --launch-profile Web . Now you should be able to browse to https://localhost:5001/ . The admin part in Blazor is accessible to https://localhost:5001/admin

Note that if you use this approach, you'll need to stop the application manually in order to build the solution (otherwise you'll get file locking errors).

After cloning or downloading the sample you must setup your database. To use the sample with a persistent database, you will need to run its Entity Framework Core migrations before you will be able to run the app.

You can also run the samples in Docker (see below).

Configuring the sample to use SQL Server

By default, the project uses a real database. If you want an in memory database, you can add in the appsettings.json file in the Web folder

Ensure your connection strings in appsettings.json point to a local SQL Server instance.

Ensure the tool EF was already installed. You can find some help here

Open a command prompt in the Web folder and execute the following commands:

These commands will create two separate databases, one for the store's catalog data and shopping cart information, and one for the app's user credentials and identity data.

Run the application.

The first time you run the application, it will seed both databases with data such that you should see products in the store, and you should be able to log in using the [email protected] account.

Note: If you need to create migrations, you can use these commands:

Running the sample in the dev container

This project includes a .devcontainer folder with a dev container configuration , which lets you use a container as a full-featured dev environment.

You can use the dev container to build and run the app without needing to install any of its tools locally! You can work in GitHub Codespaces or the VS Code Dev Containers extension.

Learn more about using the dev container in its readme .

Running the sample using Docker

You can run the Web sample by running these commands from the root folder (where the .sln file is located):

You should be able to make requests to localhost:5106 for the Web project, and localhost:5200 for the Public API project once these commands complete. If you have any problems, especially with login, try from a new guest or incognito browser instance.

You can also run the applications by using the instructions located in their Dockerfile file in the root of each project. Again, run these commands from the root of the solution (where the .sln file is located).

Community Extensions

We have some great contributions from the community, and while these aren't maintained by Microsoft we still want to highlight them.

Top 7 Web Resources built using .NET

Advantages And Disadvantages Of Tailor-made Software

If it goes to building web applications, .NET development has become a competent and reliable approach. Today, it is difficult to find a better toolset for building powerful and feature-packed Windows apps than .NET. As a matter of fact, web apps, desktop, and mobile apps, gaming and IoT solutions, and .Net stack cover them all.

That is why there is no wonder why we can find a number of corporations, that by using .NET technology have turned their software products into well-established businesses.  But what about .NET for startup development? Are there any successful startups built using the NET framework? Let’s try to find startups that have been developed by means of this technology.

.NET Startup Pros And Cons

But before we jump into today’s post, let’s resume the major .NET startup pros and cons.

  • Scalability. Scaling your startup project is really easy with .NET. Plus, the whole process of scaling is believed to be more efficient than that with Ruby, for example. In fact, if you expect your product to scale pretty fast, .NET is your best way to go.
  • Ease of use, advanced functionality, and security. ASP.NET MVC ensures safe development and makes it easier to spot mistakes and solve common problems without hassle.
  • Huge choice and space for creation. You can use multiple languages, different editors, and many libraries if you develop with .Net. As a result, many different types of applications can be built using .Net technologies.
  • One consistent API. A base set of APIs – .NET Standard is common to all .NET implementations. By the way, adopting other APIs specific to the operating systems it runs on is also possible.
  • Entity Framework . It drops the need for most data-access code developers must write regularly.
  • The possibility to benefit from Microsoft’s developers’ tools and startup programs. You can take advantage of Bizspark program , which lets you launch your business without worrying about license fees and the likes for your first years. Visual Studio Team Services allows you to have up to 5 free members.
  • No open standards. The lack of open standards significantly slows down the whole software development process.
  • Costly licensing and no open-source resources. You need to pay for the licenses to develop with this technology.
  • Platform lock-in . The developers of.Net make you too dependent on their platform.

It is of vital importance to stress that despite the mentioned above disadvantages, there are still technology companies that have chosen .NET for their startup development as they feel truly comfortable with this and other Microsoft technologies.

For example, Artelogic’s team developed an innovative multi-factor authentication platform for the startup that uses the power of 3D Facial authentification and machine learning to track down fraudulent behavior.

Still, it goes without saying that today you can hardly find anything written in one pure programming language as only in combination with the latest technologies can you stay competitive.

ASP.NET First Program Example: Hello World

Christina Tyler

ASP.NET Hello World Program with Example

Let’s look at an example of how we can implement a simple “hello world” application. For this, we would need to implement the below-mentioned steps.

Step 1) The first step involves the creation of a new project in Visual Studio. After launching Visual Studio, you need to choose the menu option New->Project.

ASP.Net Hello World Program

  • In the project dialog box, you can see various options for creating different types of projects. Click the Web option on the left-hand side.
  • When we click the Web option in the previous step, we will be able to see an option for ASP.Net Web Application. Click this option.
  • We then give a name for the application, which in our case is DemoApplication. We also need to provide a location to store our application.
  • Finally, we click the ‘OK’ button to let Visual Studio to create our project.

ASP.Net Hello World Program

Step 3) In the next screen, you have to choose the type of ASP.net web application that needs to be created. In our case, we are going to create a simple Web Form application.

  • First, choose the project type as ‘Empty’. This will ensure that we start with a basic application which is simple to understand.
  • We choose the option “web Forms”. This adds the basic folders. These are required for a basic Web Forms Application.
  • Finally, we click the ‘OK’ button to allow Visual Studio to create our application.

ASP.Net Hello World Program

If the above steps are followed, you will get the below output in Visual Studio.

ASP.Net Hello World Program

In the Solution Explorer, you will be able to see the DemoApplication Solution. This solution will contain 2 project files as shown above. At the moment, one of the key files in the project is the ‘ Global.asax.cs’ . This file contains application specific information. In this file, you would initialize all application specific variables to their default values.

Step 4) Now, it’s time to add a Web Form file to the project. This is the file which will contain all the web-specific code for our project.

  • Right-click on the DemoApplication project and
  • Choose Add->Web Form from the context menu.

ASP.Net Hello World Program

Step 5) In the next screen we are going to be prompted to provide a name for the web form.

  • Give a name for the Web Form. In our case, we are giving it a name of Demo.
  • Click the Ok button.

ASP.Net Hello World Program

Automatically Visual Studio will create the Demo Web Form and will open it in Visual Studio.

Step 6) The next step is to add the code, which will do the work of displaying “Hello World.” This can be done by just adding one line of code to the Demo.aspx file.

ASP.Net Hello World Program

Code Explanation:-

  • The Response object in ASP.Net is used to send information back to the user. So in our case, we are using the method “Write” of the Response object to write the text “Hello World.” The <% and %> markers are used to add ASP.net specific code.

If you follow all of the above steps and run your program in Visual Studio , you will get the following output.

ASP.Net Hello World Program

From the output, you can clearly see that ‘Hello World’ was displayed in the browser.
