SidebarSupport for the .NET Framework
Support for the .NET Framework 4, 4.5, and 4.5.1 ended on Jan. 12, 2016. The .NET Framework 4.5.2 is supported for the same time frame as the support life cycle of the Windows OS on which it is running. The .NET Framework 4.5.2 is supported on Windows Vista and later and Windows Server 2008 and later.
The move to the .NET Framework 4.5.2 for applications designed for the .NET Framework 4, 4.5, or 4.5.1 should not be difficult. In most cases, applications do not require code changes or recompilation unless the application needs to take advantage of new features provided by the .NET Framework 4.5.2. Organizations should test with the .NET Framework 4.5.2 to ensure that no underlying changes in the framework cause regressions in their applications.
The .NET Framework 3.5 SP1 is supported for the same time frame as the support life cycle of the Windows OS on which it is running. The .NET Framework 3.5 SP1 is supported on Windows Vista and later and Windows Server 2008 and later.
The .NET Framework 2.0 is no longer supported; it left Extended support on Apr. 12, 2016.
