Hi David,
These packages listed above are applicable to .NET Framework 4.8 product. If you use .NET Framework 4.8 Web and offline installer, we will get all updates for .NET Framework 4.8
Hi Team,
We have some issues with the “(KB5017025)”. It says that it is applicable for both .NET Framework 3.5 and 4.8.1. But when we try to install this on a machine with .NET Framework 3.5 installed, it says it is not applicable to your machine. We keep receiving this error and we were always asked to use another KB. If it is not targetted for .NET Framework 3.5, why MS keep adding this version though...
Just a random passer by, but to let you know, 3.5 is targeted, but in the context of the Windows Version given.Read more
The table has KB5017025 in the entries for Windows 10 20H2, 21H1 and 21H2, what is more is that it has it in the entries for .NET Framework 3.5 and 4.8.1. What this means is that this update is for Windows 10 versions based upon 10.0.19041 with the .NET Framework 4.8.1 update installed.
