[2023] What Is ASP.NET? A Popular Web Development Framework and Future Trends

ASP.NET is a platform every web developer knows. Announced by Microsoft in 2002, ASP.NET makes it possible to flexibly build websites, applications, and services using dynamic content.

In this article, Miichisoft explains ASP.NET's overview, why it's popular, and where development is headed next, in an easy-to-understand way.

1. What is ASP.NET?

ASP.NET is a web application framework. Created by Microsoft in 2012, it's used to support building all kinds of websites and dynamic content.

With the arrival of ASP.NET, technical developers and programmers can more easily build websites, applications, or services that use dynamic content.

ASP.NET extends the .NET platform with tools and libraries dedicated to building web applications, including:

• A framework for handling web requests in C# or F#.
• Razor, a website template syntax for building dynamic web pages in C#.
• Libraries for common web patterns such as Model View Controller (MVC).
• An authentication system with libraries, databases, and template pages for handling login information, including multi-factor authentication and external authentication via services like Google and Twitter.
• Editor extensions that provide syntax highlighting, code completion, and other features specific to web page development.

1.1. History of ASP.NET's development

ASP.NET evolved from the earlier ASP (Active Server Pages). Microsoft refined this web technology and built it into the .NET Framework, achieving a technically revolutionary leap. Two beta versions of ASP.NET were released in 2000 and 2001.

The release history of Active Server Pages is closely tied to the release of the .NET Framework.

1.2. Characteristics of ASP.NET

There are three key characteristics of ASP.NET worth noting.

• Code-behind: ASP.NET separates code from design, keeping applications maintainable. Since the platform's files are split across multiple files, developers can easily maintain aspx applications.
• Built-in state management: ASP.NET has built-in state control and management features. Since this helps web applications and services remember state, it's often used to design shopping-cart functionality for e-commerce sites.
• Caching: ASP.NET implements cache storage to improve application performance, letting information be stored, retrieved, and returned in less time.

1.3. ASP.NET's structure and components

The basic structure of Active Server Pages .NET is formed by three main layers:

• The language layer
• The library layer
• The layer that executes the programming language.

Specifically, ASP.NET plays a different role and function at each layer.

• Language layer: The ASP.NET framework is a model that lets many kinds of programming languages coexist at the same time. These programming languages support the web application development process.
• Library layer: The ASP.NET framework has a built-in standard library layer called the web library. The web library contains all the components and elements needed to support building web applications.
• The layer that executes the programming language: also called the Common Language Runtime, it handles the main tasks and acts as the language infrastructure supporting the execution of .NET/CLR programs.

1.4. Languages used in ASP.NET

ASP.NET supports many programming languages, including C#, Visual Basic.NET, and JavaScript. C# and VB.NET are the most widely used for web application development.

1.5. Frequently asked questions about ASP.NET

2. Why ASP.NET is a preferred framework for web development

2.1. ASP.NET used for building websites and web apps　

It's widely used for building websites and web apps for the following reasons.

2.2. Advantages

• High-performance apps: since the release of .NET 6, ASP.NET's performance has improved, and it runs faster than many other popular web frameworks. Performance reports are available from TechEmpower Round 20.
• Application/software security: ASP.NET protects applications from malicious scripts (XSS) and cross-site request forgery (CSRF). It includes a user database that supports multi-factor authentication and external authentication via services like Google and Twitter.
• Diverse applications: by investing in ASP.NET, companies can use its rich set of libraries and tools to develop many different types of application solutions, including AI-based apps, IoT-based apps, and game development.
• Moving business to the cloud: ASP.NET lets companies build premium cloud applications. By leveraging Microsoft Azure, existing .NET applications can now be migrated to the cloud.
• Building high-performance mobile apps: Xamarin.Forms is Microsoft's mobile UI framework for developing iOS, Android, and Windows mobile apps with .NET from a single shared codebase.
• Access to an active community: ASP.NET has many active communities. Companies can get quick answers to technical questions and discuss ASP.NET through active communities such as Stack Overflow, the ASP.NET Forums, .NET Tech, and The .NET Docs Show. Good SEO support: fast page load speed and higher performance make it very useful for the SEO every business needs.

2.3. Disadvantages

Despite its many advantages, ASP.NET also has some drawbacks:

• Because ASP.NET is designed by Microsoft, any changes Microsoft makes will inevitably affect application development projects built on the .NET Framework.
• Migrating applications to .NET can be costly.
• Migrating older app versions to newer ones can be time-consuming and difficult.

That said, given the benefits ASP.NET brings, these drawbacks are arguably minor.

3. Recent demand for ASP.NET development and future outlook

3.1. Recent demand for ASP.NET development

Even as technology evolves, ASP.NET has consistently remained popular. Most software development companies use this powerful framework to build dynamic websites, web services, cloud-based web applications, and other web applications.

3.2. ASP.NET development trends over the next 5 years

With the recent release of .NET 6, the future looks quite bright.

Check out the .NET roadmap below. The Microsoft team is constantly working on improvements and delivering something new each time.

Reference: Microsoft

♦ ASP.NET developers can build fast, scalable cloud applications on Microsoft Azure.

♦ With Azure cloud, companies no longer need to worry about servers and only pay for the resources their application actually uses at runtime. The serverless PC market is expected to reach a CAGR of over 23.17% during the forecast period (2021-2026).

♦ Thanks to Xamarin, more companies will invest in developing Android and iOS applications with .NET and C# in the future.

♦ In the future, companies will leverage .NET to build 2D and 3D applications such as games and simulations.

♦ With ML.NET 1.4, companies will see countless AI applications emerge.

♦ In the near future, ASP.NET will run smoothly with Docker, letting developers deploy ASP.NET-based applications faster.

♦ By adding the .NET IoT library to the .NET Framework, developers will be able to build applications that run on IoT devices.
