MC352543: .NET Framework 4.5.2, 4.6, 4.6.1 will reach end of support in 2022

On April 26, 2022, the .NET Framework 4.5.2, 4.6, and 4.6.1 will reach end of support, and after this date, Microsoft will no longer provide updates including security fixes and technical support for these versions. There is no change to the support timelines for any other .NET Framework version, including .NET 3.5 SP1, which will continue to be supported as documented on our .NET Framework Lifecycle FAQ.

Note: Windows 10 Enterprise LTSC 2015 was 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 4.6 on Windows 10 Enterprise LTSC 2015 through end of support of the OS version (October 2025).

When this will happen

.NET Framework 4.5.2, 4.6, and 4.6.1 will be reaching end of support on April 26, 2022. This framework was previously digitally signed using certificates that use the Secure Hash Algorithm 1 (SHA-1), which is no longer deemed secure, and we are prioritizing support to newer digital certificates.
