About the .NET Framework

The .NET Framework is a runtime execution environment that manages applications that target the .NET Framework. It consists of the common language runtime, which provides memory management and other system services, and an extensive class library, which enables programmers to take advantage of robust, reliable code for all major areas of application development.

The .NET Framework for users

If you do not develop .NET Framework applications, but you use them, you are not required to have any specific knowledge about the .NET Framework or its operation. For the most part, the .NET Framework is completely transparent to users.

The .NET Framework for developers

If you are a developer, you can choose any programming language that supports the .NET Framework to create your application. Because the .NET Framework provides language independence and interoperability, you can interact with other .NET Framework applications and components regardless of the language with which they were developed.

See Getting Started with the .NET Framework and What's New in the .NET Framework 4.6.1.

    • When WSUS server is synchronized with Microsoft Update server or Microsoft Update Catalog site for importing updates, you will see that there are two updates with the .NET Framework 4.6.1 being published for each platform.
