I found this answer on my search for the same error, so I'll answer it for the next ones coming here.

Look at the last 2 commands in your script:

- dotnet build --no-restore --configuration Release
- dotnet test --no-build --no-restore -v d

You are building in Release configuration but are testing in Debug configuration.

So the dotnet test command doesn't find any assemblies for running tests due to the --no-build switch.

In this case I think it would have been much more helpful for you (and me) if the error message had been a "file not found" instead of the less specific "argument is invalid".
