When a user runs an application, the code for that application is actually compiled into machine code at runtime and then executed. CLR also provides some other services, such as managing memory and processor threads, handling program exceptions, and managing security. The runtime environment is really a way of abstracting the application from the actual hardware on which the application runs. In a nutshell, .NET consists of the runtime environment, compilers, languages, and base class libraries. Each application model caters to specific types of applications like the cloud, web, desktop, mobile, etc.
The framework includes a variety of programming languages, such as C#, F#, and Visual Basic, and supports a range of application types, including desktop, web, mobile, and gaming applications. The .NET Framework (pronounced as “dot net”) is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows. It was the predominant implementation of the Common Language Infrastructure until being superseded by the cross-platform .NET project. It includes a large class library called Framework Class Library and provides language interoperability across several programming languages. Programs written for .NET Framework execute in a software environment named the Common Language Runtime . The CLR is an application virtual machine that provides services such as security, memory management, and exception handling.
What Is the Microsoft .NET Framework, and Why Is It Installed on My PC?
To help you set up quickly, you can install the .NET Coding Pack, which includes VS Code, the .NET Software Development Kit, and essential .NET extensions. The Coding Pack can be used as a clean installation, or to update or repair an existing development environment. Use Visual Studio Code with the C# and F# extensions to get a powerful editing experience with C# IntelliSense, F# IntelliSense , and debugging. The .NET runtime, also called Common Language Runtime , compiles and executes .NET programs on different operating systems. Users can choose different components to meet their software development requirements. CTS and the CLR used in .NET Framework also enforce type safety.
In easy words, it is a virtual machine for compiling and executing programs written in different languages like C#, VB.Net, etc. Microsoft’s flagship programming language, Visual Basic finds its way into many Microsoft development applications. Visual Basic is intentionally designed to be easy to learn and easy to use.

The CLR also provides other important services such as security, memory management, and exception handling. The class library and the CLR together constitute the .NET Framework. It provides language interoperability because of which each language can be used in other languages. The dot net framework consists of a class library, which is named as Framework Class Library . It follows the design principle of interoperability, language-independent, type safety, portability, security, memory management, and performance. The ASP.NET framework extends the .NET developer platform specifically for building web-based applications.
As we mentioned above, .NET uses the object-oriented programming language model. This model is centered around objects rather than “actions” and data rather than logic. The support of data-oriented software application development in .NET Framework and Core are provided by the Entity Framework. ASP.NET. While the previous two components are designed for desktop engineering ASP.NET is used to develop dynamic websites and web applications.
What are .NET programming languages?
Start your programming journey with an introduction to the world of code and basic concepts. Since it’s more flexible and Microsoft is actively enhancing this version, we’ll be using this one throughout the path. There are three significant phases of the development of .NET technology. An enterprise content management What is .NET and project management system geared toward creating usable platforms. As an open-source solution, it has the support of an extremely large community and has experienced many improvements throughout the years. C#, F#, and Visual Basic programmers can all benefit from the knowledge of the .NET platform.
- High Performing – .NET applications are very fast and provide quick responses and consume fewer resources.
- Visual Studio is integrated with .NET and provides the features of a language-specific environment.
- It can target different types of devices like PCs, tablets, phones, Xbox, etc.
- C#, F#, and Visual Basic programmers can all benefit from the knowledge of the .NET platform.
- Windows 8 and Windows 10 include versions 3.5 and 4 (the current version right now being 4.6.1).
The ability to reuse code between implementations reduces the cost of development. Different .NET implementations can reuse the same code and libraries. Each implementation uses both .NET standard APIs and unique APIs specific to the operating systems it runs on. However, Mono has provided support for SIMD Extensions as of version 2.2 within the Mono.Simd namespace in 2009. Mono’s lead developer Miguel de Icaza has expressed hope that this SIMD support will be adopted by CLR’s ECMA standard. Streaming SIMD Extensions have been available in x86 CPUs since the introduction of the Pentium III. Some other architectures such as ARM and MIPS also have SIMD extensions.

Instead of an app on your computer, the SDK is accessed via a command-line interface — to use an SDK, you’ll open up a terminal on your computer and type commands instead of clicking buttons. In this example, you can see a terminal in which the user ran commands like dotnet new and dotnet run to build a new application, then ran it (the app just prints out “Hello World!”). F# is an object-oriented programming language designed for general-purpose, function-first programming. For JavaScript programmers interested in learning more about .NET, F# could be a useful language. F# is largely intended to bring functional programming to .NET. Though .NET does support programming in C#, F#, and Visual Basic, it doesn’t support all major programming languages.
CIL code looks different because it is a lower-level machine code language. C# is a simple, modern, and object-oriented programming language. With syntax similar to the C family of languages, C# is familiar to C, C++, Java, and JavaScript programmers. Portable.NET provides an implementation of CLI, parts of FCL, and a C# compiler. The project was discontinued, with the last stable release in 2009.

Fortunately, things are smoother in modern versions of Windows. Sometime during the Windows Vista days, two important things happened. That version was reworked to include components from versions 2 and 3. Apps that required earlier versions would now work if you just had version 3.5 installed.
However, this did not apply to the part of the .NET Framework not covered by ECMA-ISO standards, which included Windows Forms, ADO.NET, and ASP.NET. Patents that Microsoft holds in these areas may have deterred non-Microsoft implementations of the full framework. In April 2019, Microsoft released .NET Framework 4.8, the last version of the framework as a proprietary offering. Only monthly security and reliability bug fixes to that version have been released since then. Unless you’re a developer, you don’t need a lot of knowledge to make use of it.
Introduction to .NET Framework
GC runs only when a set amount of memory has been used or there is enough pressure for memory on the system. Since it is not guaranteed when the conditions https://www.globalcloudteam.com/ to reclaim memory are reached, GC runs are non-deterministic. Each .NET application has a set of roots, which are pointers to objects on the managed heap .
