NET Framework versions signed using the legacy and insecure Secure Hash Algorithm 1 will reach end of support next year.
NET Framework 4.5.2, 4.6, and 4.6.1 will reach end of support on April 26, 2022," said Jamshed Damkewala,.
NET Framework 4.6 version that ships with Windows 10 Enterprise LTSC 2015, which will get its support extended to October 2025, when the OS reaches its end of life.
NET Framework 4.6.2 or later versions of their apps are only required to update the runtime on which the apps are running to at least version 4.6.2 to stay supported.
"If your application was built to target.NET Framework 4 - 4.6.1, it should continue to run on.NET Framework 4.6.2 and later without any changes in most cases," Damkewala added, without a need to recompile or retarget.
NET Framework versions because they are digitally signed with certificates that use the legacy SHA-1 cryptographic hashing algorithm, which is now insecure.
