What Is ASP.NET? Introduction, Features, And Tutorials

Microsoft developed its Active Server Pages Network Enabled Technologies (ASP.NET) web application framework to allow developers to create web applications, dynamic websites, and web services. ASP.NET is built on the Common Language Runtime (CLR), which lets developers write ASP.NET code using any supported .NET language. 

First released in 2002, ASP.NET has become one of the most popular web development frameworks, with millions of websites and applications built using ASP.NET. The following guide is an introduction to ASP.NET and a general overview of what it can do.

What Are The Main Features Of ASP.NET?

ASP.NET provides many features that make ASP.NET an ideal choice for developing business software applications. The following are some of these features:

  • A rich set of controls and libraries for building user interfaces
  • Easy integration with existing Microsoft technologies such as Active Directory and COM+
  • Support for industry standards, including XML, SOAP, and HTML
  • A robust security model that you can customize to fit the needs of your application
  • Its open-source design makes it easy to integrate with other applications and systems
  • Mobile controls make it easy to create mobile-friendly websites
  • Full support from Microsoft through regular updates and security patches

Getting Started With ASP.NET

Getting started with ASP.NET is much easier than you might realize. In fact, it's user-friendly nature is one of the reasons it's such a popular web development framework. Microsoft does have a basic ASP.NET tutorial available on its website, although there are more in-depth guides to ASP.NET available online as well. With that in mind, the following are the general steps you'll need to take to get started with ASP.NET:

Installing The Software

The first thing you'll need to do is to install the latest version of .NET. .NET is a software framework from Microsoft that provides a programming environment for building and running ASP.NET applications. You can download the latest version, .NET 5, from the Microsoft website.

Once you have .NET installed, you can start developing ASP.NET applications using any text editor or integrated development environment (IDE) of your choice. Visual Studio is a popular IDE for ASP.NET development, but you can also use open-source alternatives like SharpDevelop or MonoDevelop. 

You can download the free Visual Studio Community edition from the Microsoft website if you don't have Visual Studio.

Creating Your First Project

Once you have installed the software, launch the IDE you've chosen. For example, launch Visual Studio to create a new ASP.NET web forms project. After you have done so, follow these steps to create your first project:

 1. Create A New Project

Open Visual Studio and select "File" > "New" > "Project" from the menu. In "New Project," choose the "ASP.NET Web Forms Application" option from the list of templates and click "OK".

2. Configuring Information

In the "Configure Your New Project" dialog, you will need to provide a name and location for your project. You can also select the version of ASP.NET you want to use for your project. Once you enter the information for your project, click "OK" to continue.

3. Open Up The "Default.aspx" Page

After creating the project, Visual Studio will open up the "Default.aspx" page in the editor window. This page is the starting point for your ASP.NET website and contains the default HTML code that Visual Studio generates

4. Run Your Application

You can now run your application by selecting "Debug" > "Start Without Debugging" from the menu or by pressing “Ctrl+F5” on your keyboard. Next, Visual Studio will launch a web browser and navigate to the "Default.aspx" page of your website.

You should now see the default ASP.NET web page that Visual Studio generated for you. Once this occurs, you have successfully created your first ASP.NET website!

Tips For Developing High-Quality ASP.NET Websites And Applications

Now that you've got the basics down, here are some tips to help you develop high-quality ASP.NET websites and applications:

  • Use The Latest Versions Of ASP.NET And Visual Studio: New versions of ASP.NET and Visual Studio are frequently released, which commonly include new features and performance improvements.

For instance, ASP.NET Core is cross-platform, whereas older ASP.NET versions are not. Although older versions are still used and supported, if you're just starting out, then you might as well get the most current versions of both.

  • Take Advantage Of ASP.NET MVC: ASP.NET MVC is a newer framework for developing ASP.NET applications, and offers many advantages over the traditional Web Forms approach. These advantages include better separation of concerns, easier unit testing, and more control over the markup. If starting a new project, you should consider using ASP.NET MVC.
  • Use Caching Judiciously: Caching can dramatically improve the performance of your website or application. It does this by storing frequently-accessed data in memory so that it doesn't have to be retrieved from the database whenever needed. However, be careful not to cache too much data, as this can result in memory issues.
  • Optimize Your Database Queries: Database queries can often be the bottleneck in an ASP.NET application. If your application is slow, it's worth looking at your database queries to see if they can be optimized. 

For example, suppose you're retrieving more data than you need. In that case, you can use the "select" statement to specify only the columns you want.

  • Handle Errors Gracefully: Errors will inevitably occur in your application at some point. When they do, you’ll want to ensure that the errors are handled gracefully so that your users don't see a big, ugly error message.

ASP.NET provides several ways to handle errors, such as using the "Try...Catch" statement, custom error pages, and the built-in health monitoring system.

Other Tools Or Frameworks That Work Well With ASP.NET

ASP.NET is just one of many tools or frameworks you can use for developing web applications. Here are some other types of frameworks and tools that work well with ASP.NET:

  • jQuery: jQuery is a popular open-source JavaScript library that makes adding interactive features to your websites and applications easy. It's also used by many of the built-in AJAX controls in ASP.NET. It works across a wide range of browsers.
  • Bootstrap: Bootstrap is an open-source CSS framework that makes it easy to create responsive, mobile-first websites and applications. You can use it with ASP.NET to create great-looking websites that work well on all devices.
  • Vue.js: Vue.js is an open-source JavaScript framework that makes it easy to create reactive user interfaces. As such, it's a popular choice for developing single-page applications.
  • React: React is an open-source JavaScript library for building user interfaces. It is used by Facebook and Instagram (and maintained by Meta along with a large community of developers) and can be used with ASP.NET to create modern web applications.

How Does ASP.NET Compare To Other Web Development Frameworks?

ASP.NET is a widely used web development framework that enables developers to create well-structured, maintainable, and testable code. It also provides excellent flexibility and extensibility, allowing developers to create custom controls and modules to meet their specific needs. 

Of course, there are other web development frameworks that you can use, such as Ruby on Rails and Django, all of which offer their own advantages. Ultimately, it's up to the individual developer to decide which framework is right for them. However, it's worth noting that ASP.NET has the following advantages over other web development frameworks:

ASP.NET Is Built On Top Of The .NET Framework

The .NET Framework is a powerful, enterprise-grade framework that provides rich features and functionality. Because ASP.NET is built on top of the .NET Framework, it inherits all of these features and benefits. As a result, ASP.NET is a great choice for developing large-scale, enterprise-grade web applications.

ASP.NET Offers More Support Than Other Frameworks

There is no doubt that Ruby on Rails and Django are popular web development frameworks. However, ASP.NET has more support than both of these frameworks. 

For example, more books, online tutorials, and third-party components are available for ASP.NET than for Ruby on Rails and Django. This means you are more likely to find the resources you need when developing with ASP.NET. 

ASP.NET Is Backed By Microsoft 

Microsoft is the primary vendor behind ASP.NET, which means you can expect great support from them. They offer free software updates, online documentation, and various support options. This is crucial because it means you can always get the help you need when developing with ASP.NET compared to Personal Home Page (PHP) and other web development tools.

ASP.NET Over The Years And Where It Is Headed Next 

ASP.NET has been around for many years and is constantly evolving to meet the needs of modern web development. In 2016, Microsoft released ASP.NET Core, a major update to the framework that included a new modular design, improved performance, and support for cross-platform development. ASP.NET Core 5 (released in 2022) is the latest version of the framework.

ASP.NET continues to be one of the most popular web frameworks amongst developers, as evidenced by the 2021 Stack Overflow Survey. In the survey, 15.7% of developers preferred ASP.NET as their go-to web framework, while 18.1% preferred ASP.NET Core. This means that over 30% of developers prefer a version of Microsoft's web framework over any other web development platform.

It's evident that ASP.NET is here to stay and will continue to be a popular choice for web development in the years to come. Additionally, Microsoft is committed to continuing the development of ASP.NET, and will likely continue to release new versions in the future.

Develop Your Website Using The Best Practices!

ASP.NET is a great choice for developing websites because it allows you to create well-structured, maintainable, and testable code. Additionally, you can extend the framework to meet your specific needs. However, remember to always follow best practices when developing your website. Doing so will ensure that your website is scalable, reliable, and easy to maintain.
