I am using Visual Studio Enterprise 2017 to develop my .net core projects.
My solution also has some unit test projects and I want to view my current Code coverage.
Based on this article (Code Coverage does not work in the IDE with netcoreapp1.x projects (VS 2017 RTM):
Code coverage is currently not implemented for netcore projects. The work on this issue is in progress, it will come as part of post RTW releases.
