.NET Framework is a run-time execution environment that manages .NET Framework-targeted applications. It comprises a common language runtime, which offers memory management and other system services, and a large class library, which allows programmers to use strong, dependable code in all main areas of app development.
Microsoft’s.NET Framework is a platform for software developers that includes runtime services, base class libraries that may be used in your code, numerous tools to assist with software development activities, and support for more than one programming language. The .NET Framework is a component of the.NET Platform, which was initially launched in 2002 and has since improved and evolved with several revisions over the years. .NET is a mature platform today, but it is always evolving with upgrades and new features.
.NET Framework 4.8 is the most recent and recommended version of the.NET Framework for application development. The.NET Framework is included with the Windows operating system.

INFORMATION
.NET Framework-targeted applications.is a controlled execution environment on Windows that offers various services to the programmed that run in it. Development framework, common type system, memory management, and other services are offered to.NET Framework applications. The major purpose of the .NET Framework is to create an environment in which WEB developers can develop, execute, and test their applications, and consumers may run applications designed for the .NET framework.
Microsoft also supplies Visual Studio, an integrated development environment (IDE) for designing, developing, and running.NET framework applications.
The.NET SDK, which can be downloaded here, includes a library of proven, reusable code that developers may use in their own applications. The following are the services that the .NET Framework delivers to running apps.
Memory administration. Many programming languages use the term program standard type system. The compiler defines fundamental types in traditional programming languages, complicating cross-language compatibility. The .NET Framework type system defines basic types in .NET Framework, which are shared by all languages that target.NET Framework.
A large class library. Instead of writing massive amounts of code to handle typical low-level programming activities, programmers leverage the .NET Framework Class Collection’s conveniently available library of types and their members.
ABOUT
ASP.NET for online apps, ADO.NET for data access, Windows Communication Foundation for service-oriented apps, and Windows Presentation Foundation for Windows desktop apps are examples of development frameworks and technologies included in the.NET Framework Interoperability of languages. Language compilers for the .NET Framework generate an intermediate code known as Common Intermediate Language (CIL), which is then compiled at run time by the common language runtime. This feature allows functions built in one language to be available to other languages, allowing programmers to concentrate on developing programmes in their chosen languages.
Compatibility with previous versions. With a few exceptions, programmed written with a certain version of the .NET Framework operate without change on a subsequent version.
Version conflicts can be avoided by running various versions of the common language runtime on the same machine. Multitargeting. Developers construct class libraries that function on multiple.NET Framework platforms supported by that version of the standard by targeting.NET Standard. Libraries targeting.NET Standard 2.0, for example, may be utilized by programmed targeting .NET Framework 4.6.1,.NET Core 2.0, and UWP 1.
