After upgrading to Visual Studio 2019 - 16.8.2 and installing .NET 5.0 SDK - I have noticed that my Target Frtamework dropdown ont he project properties is grayed out.
The screenshot below is for a .NET Core 3.1 console app. Any pointers as to what might be causing this are greatly appreciated.
Same problem here. Just installed VS2019 v16.9 preview 1 to bypass the problem and it's ok with this one. The problem still exist with v16.8.2.
16.9 preview 1
Ok, looks like uninstalling all of the .NET core SDKs from Add/Remove programs has resolved the issue.
We tried reinstalling .net core SDK 3.1 and it did not work.
The only thing that's actually working for me is to use the vs installer to repair the vs. Here's how to make it work using Microsoft docs. here
