What Is ASP.NET And Why It Is Used

ASP.NET is a platform for web development and the Microsoft .Net platform part. ASP.NET applications are written using extensible and reusable components or objects found in the .Net framework. They use the entire class hierarchy in the .Net framework.

ASP.NET provides:

  • The programming model.
  • End-to-end software infrastructure.
  • Services you need to build robust web applications for desktops and mobile devices.

ASP.NET runs on top of the HTTP protocol and uses HTTP commands and policies to establish two-way communication and interaction between the browser and the server.

When writing ASP.NET application code, the following languages ​​are used:

  • FROM;
  • Visual Basic.Net;
  • JScript;
  • J#.

ASP.NET is used to create interactive data-driven web applications over the Internet. It consists of many controls such as text fields, buttons, and labels for building, configuring, and manipulating code to create HTML pages.

What is ASP.NET Core?

ASP.NET Core is an updated version of ASP.NET and runs on all major computing platforms, including Windows, macOS, and Linux. Like ASP.NET, it is an open-source code created by Microsoft that allows developers to create web applications, web services, and websites driven by dynamic content. First released in 2016, ASP.NET Core is relatively new but has already received version 2.0 and is now a stable alternative to ASP.NET web applications hosted on Windows. Developers familiar with ASP.NET can use their existing knowledge of C# and quickly understand the differences between frameworks introduced in ASP.NET Core.


We are confident that we have what it takes to help you get your platform from the idea throughout design and development phases, all the way to successful deployment in a production environment!

In general, ASP.NET Core has some advantages:

  • a fast, lightweight, high-performance web framework;
  • supports modern client frameworks like AngularJs, ReactJs, and React with Redux and client framework patterns like AngularJs, ReactJs and React with Redux, etc.;
  • can be hosted on IIS, Apache, Docker, or self-hosted;
  • cross-platform applications that run on Windows, Mac, and Linux development tools;
  • supports built-in dependency injection and modular HTTP requests;
  • an open-source web framework focused on the community;
  • ASP.NET Core runs on .NET Core, which supports multiple running versions of applications simultaneously;
  • has a single creation history of the web interface and web API.

ASP.NET is .NET Extension

ASP.NET extends the .NET platform with tools and libraries specifically designed for building web applications.


There is an extensions list of ASP.NET to the .NET platform:

  • A basic framework for handling web requests in C# or F#;
  • A web page template syntax is known as Razor for creating dynamic web pages using C#;
  • Libraries for common web patterns such as Model View Controller (MVC);
  • The authentication system includes libraries, databases, and template pages for handling logins, including multi-factor authentication and external authentication with Google, Twitter, etc.

Editor extensions provide syntax highlighting, code completion, and other features specifically designed for web development.

When using ASP.NET, your back-end code, such as business logic and data access, is written using C#, F#, or Visual Basic.

Because ASP.NET extends .NET, you can use the vast ecosystem of packages and libraries available to all .NET developers and create libraries shared by any application written in the .NET platform.

ASP.NET Benefits

There are some advantages of ASP.NET that make it superior to other platforms available in the market.

  • A robust set of tools and a Visual Studio IDE designer supports the ASP.NET platform. Drag and drop server controls and automatic deployment are among the features offered by this versatile tool.
  • The platform lowers the higher costs and builds native web applications with all the features.
  • The most recent ASP.NET open-source, cross-platform framework is ASP.NET Core, a cloud web application connected to the Internet.
  • The ASP.NET Core encourages efficient web applications creation and mobile and IoT applications.
  • These applications provide increased efficiency by taking advantage of early binding, just-in-time compilation, built-in optimizations, and caching right out of the box.
  • ASP.NET significantly reduces the code required to build large-scale applications with improved security and performance.
  • Less code makes the application easy to manage and maintain efficiently.
  • Windows authentication makes the apps secure.
  • In ASP.NET applications, source code and HTML files are combined so that pages are easy to manage and write. The source code runs on the computer and gives websites great power and versatility.
  • ASP.NET is strictly server-side programming, so the code will be executed before sending it to the browser.
  • Apps are language-independent, so the language choice works best.
  • All processes are monitored and handled by the ASP.NET runtime, which means that if a process is dead, a new method can be spawned in place, helping to keep applications always ready to process requests.
  • ASP.NET reduces web application building hassles, such as speed, cost, and language, and provides several development modes that simplify and enhance application development.
  • ASP.NET runs over HTTP and uses its commands, provides a platform and allows writing code in a text editor program and Visual Studio .NET.
  • The web application must be accessible from anywhere in the world. So the language, date and time format, number format, and currency must be different for different regions or countries. ASP.NET supports globalization so that clients from other countries can access the application. You can customize the application for different languages using resource files. These files act as a central repository where all texts are placed.

If you’re building an application, ASP.NET might be your best bet because it’s faster and more efficient than other technologies.

Why Should We Use ASP.NET?

The crucial use cases of ASP.NET given below:

  • Due to the wide variety of ASP.NET features and functions, it is widely used. Safety is first and foremost. Suppose we logged into a bank account and then went to different websites. If other websites do money transfers, that isn’t good. So ASP.NET does indeed have a perfect structure that prevents cyber-attacks like this.
  • ASP.NET supports caching, making it easy to specify how long any request should be cached via a generic HTTP header.
  • ASP.NET is a server-side technology that compiles code, resulting in better performance. It also reduces the number of code lines needed to build large applications.
  • Popular websites such as amazon.com, eBay, and others use ASP.NET for their development. The webserver monitors and notices memory leaks, infinite loops, and illegal activities. It constantly monitors web components and application pages. Once it finds any of those activities, it will destroy them and restart the system.
  • ASP.NET pages are easy to write and maintain because of the source code and HTML codes. Since the source code is executed on the server-side, this results in robust and flexible web pages.
  • WebForms provide a rich set of server controls that run when a page is requested and display markup in the browser. Some web server controls are similar to HTML buttons and text fields. It also provides rules that we can use to connect to data sources and display data.

All in all, ASP.NET is an excellent platform for developing websites and web applications. It’s reliable, fast, easy to use, accessible, and widely known. ASP.NET gives complete control over development and can be used on any project, big or small.
