Answer 1

Got this error, when trying to debug a unit test. Below are the steps I tried.

• Step 1: Installed Microsof.TestPlatform.TestHost and tried to run the test but no luck.
• Step 2: Changed Target framework from .NET Core 2.0 to 2.1 and tried to run the test but no luck.
• Step 3: Closed and opened VS2017 and tried to run.

Yay!!! it worked :-) Never miss to try the last step ;-) Hope this helps someone like me.
