OpenCover keeps saying "No results, this could be for a number of reasons" for .NET Core

Question

When I run OpenCover.Console.exe, it runs tests, but code coverage is failing:

What's wrong? How to fix it?

Answer 1

Make sure that build settings Debugging information for that project is set to Full(Project->Properties->Build->Advanced).

The same can be done by modifying .csproj file and adding <DebugType>Full</DebugType> node under <PropertyGroup>.
