title: Dotnet Unit test with Coverlet- How to get coverage for entire solution and not just a project
body: <p>We are using coverlets (<a href="https://github.com/tonerdo/coverlet" rel="noreferrer">https://github.com/tonerdo/coverlet</a>) for measuring code coverage of unit tests in a .NET solution containing multiple projects. The results are appearing separately for every project in the solution. What we want is to have a consolidated result for the entire solution. 
  Can anyone suggest the best way to get that? 
  If by any chance it is not possible by coverlet can you suggest any alternate open source tool that can do this using a CLI. We essentially need to integrate it with a CI tool, which should warn if the coverage is below a threshold.</p>
