CI is broken, failing with messages:

I think what's happening is that the default test assembly discovery is matching anything with "test" in its name, and is therefore pulling in Microsoft.TestPlatform.CoreUtilities.dll, Microsoft.TestPlatform.PlatformAbstractions.dll, Microsoft.VisualStudio.TestPlatform.ObjectModel.dll and testhost.dll, none of which can be exectuted for the reasons listed.

This PR makes the test assembly explicit, which should hopefully address the above issues.

Also, run tests in parallel.

Yep, that fixed it. No idea what broke it. Something must have changed on Azure Pipelines.
