End of support for .NET Framework 4.5.2, 4.6, and 4.6.1 in April 2022

Posted on 2021-04-28 by guenni

[German]In the developer blog, Microsoft informed about the expiring support for the .NET Framework versions 4.5.2, 4.6 and 4.6.1 on April 26, 2021. Their support will end on April 26, 2022, one year from now. Then there will be no more security updates. The exception is Windows 10 Enterprise LTSC 2015, because .NET Framework 4.6 is integrated in this operating system. This operating system version is an LTSC version (Long Term Servicing Channel). Microsoft will continue to support .NET Framework 4.6 on Windows 10 Enterprise LTSC 2015 until the end of support for this operating system version (October 2025). .NET Framework 3.5 SP1, on the other hand, will continue to receive support until Jan. 9, 2029.
