Microsoft will stop supporting multiple versions of the .NET Framework next year, specifically those that use SHA-1 for digital signatures.
NET Framework is a free development framework for creating .NET applications, websites, and more. The thing works on multiple operating systems but is mainly known from Windows. Versions 4.5.2, 4.6 and 4.6.1 will not be supported next year, most likely from April 26, 2022. Microsoft is writing this in a blog.
As with older versions of operating systems and software suites, this means for Microsoft that it will not conduct new security updates to .NET Frameworks starting next year, nor provide technical support for the software. The only exception is .NET Framework 4.6 which is stored in Windows 10 Enterprise LTSC 2015. It is still supported as long as the OS receives support from Microsoft.
Microsoft suggests moving to at least .NET Framework 4.6.2 or later by next year. Applications built on older frameworks must, in many cases, be compatible with newer ones.
The reason for withdrawing these versions is the signature mechanism. Older versions used SHA-1 (Secure Hash Algorithm 1) for certificates. It is a fairly outdated encryption algorithm that is no longer perceived as secure. Microsoft has replaced the system in newer apps with the slightly stronger SHA-2. Earlier, the company also pulled all of its own apps that use SHA-1 from Microsoft’s Download Center.
