.NET Framework is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library called Framework Class Library (FCL) and provides language interoperability across several programming languages.

On operating systems prior to Windows 10 version 1809 and Windows Server 2019, .NET 3.5 SP1 assumes the same lifecycle policy as the underlying OS on which it is installed.

More information is available on the .NET Framework website.
