My solution contains a native C++ project. If I try to run a unit test from the C# test project, I get the following output:
========== Discover test finished: 0 found (0:00:04,2581721) ==========
------ Discover test started ------
Assembly not supported: D:\GXR\Pacific\Bin\ProcessCrashToolkit.Native_ur.dll
An exception occurred while test discoverer 'NUnitTestDiscoverer' was loading tests. Exception: Object reference not set to an instance of an object.
========== Discover test finished: 0 found (0:00:00,779885) ==========
Please note that I try to start a unit test from a totally different (C#) project.
If I open the Test Explorer and rebuild the solution, I get the same error output.
