No error is reported in Text Explorer if the test assembly fails to load.

If a missing dependency causes a FileNotFoundException in the project being tested, the adapter immediately quits without updating any test results. Is there some way it could report a failure besides the Output window?

I hate to admit it, but I think this is the third time I've gone down an hour-long rabbit trail thinking something was very wrong with the adapter before realizing what was going on.

Hi, @jnm2, @CharliePoole.

I have a similar problem.
I use the dotnet test command to run .NET Core tests, because nunit3-console isn't compatible with .NET Core tests (#364).
When NUnit cannot find the version of the package that is registered in .csproj, the following error occurs:

But at the same time she does not return an error, although it should not be so.

I also tried to run tests through visual studio and it showed me that tests inconclusive and skips him.

To repeat this error simply in the folder where all the dlls are stored, download and manually place NUnit version 3.11.0.

Do you have the exact same issue or do I need to create a separate issue?
