I am upgrading to VS2022 from VS2019. We had some 1000+ test cases already written which we are able to execute on VS2017 and VS2019 but when I open the project in VS2022, test cases do not run. It takes less than a millisecond and the status bar says "Test run finished 0 tests, (0 passed, 0 failed, 0 skipped run in <1 ms
There is 1 error icon reported on Text Explorer ad after cligking that icon or when I try to "debug" an individual test, I get following error in the Output window

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

What I have tried so far
System Info: Microsoft Visual Studio Professional 2022 (64-bit) Version 17.7.1 (latest) OS Name Microsoft Windows Server 2019 Standard Version 10.0.17763 Build 17763
Cam anyone put me in the right direction please?
I encountered this problem as well, when I upgraded from Visual Studio 17.6.6 to 17.7.1.
I upgraded the "Microsoft.NET.Test.Sdk" NuGet package to 17.7.1 (previously I was using 16.4.0), which resolved the issue and allowed me to run the tests in Visual Studio again.
