.NET Framework 4.5.2, 4.6, and 4.6.1 will reach end of support* on April 26, 2022. After this date, we will no longer provide updates including security fixes or technical support for these versions.

Customers currently using .NET Framework 4.5.2, 4.6, or 4.6.1 need to update their deployed runtime to a more recent version – at least .NET Framework 4.6.2 before April 26, 2022 – in order to continue to receive updates and technical support.

*Windows 10 Enterprise LTSC 2015 shipped with .NET Framework 4.6 built into the OS. This OS version is a long-term servicing channel (LTSC) release. We will continue to support .NET Framework 4.6 on Windows 10 Enterprise LTSC 2015 through end of support of the OS version (October 2025).

There is no change to the support timelines for any other .NET Framework version, including .NET Framework 3.5 SP1, which will continue to be supported as documented on our .NET Framework Lifecycle FAQ.
