VS 2017 not discovering unit tests for NC 4.0

I Downloaded VS 2017 & NC 4.0 . I also installed Test Dapater  for Nunit3.0 in Extension and Updates but the test explorer just wont show the unit tests as it was with 3.9 on vs2015 .

I also got the same issue, tried following steps and it worked:

1. Update Visual Studio to latest version.
2. Install "Nunit 3.0 test adapter" from Extension and Updates.
3. Go to Test --> Test Settings --> Default Process Architecture --> Select x86 or x64 (if not selected)
4. Close ALL instances of Visual Studio and re-run, build the project. Test cases will appear in test explorer.

Thanks a lot for the reply....

I was only able to get those unit tests at the 4th attempt by repeating above steps..


I had kept using nunit Gui as secondary options...
