DirectoryNotFoundException when measuring code coverage

[Georgi-Ivanov-Fourth]

I have set of XUnit tests using EntityFramework.Testing package and when I run them using xunit runner everything is OK:

C:\WhateverProject>.\packages\xunit.runner.console.2.2.0\tools\xunit.console.exe ".\WhateverProject.UnitTests\bin\Release\WhateverProject.UnitTests.dll" -xml TestResults.WhateverProject.xml
xUnit.net Console Runner (64-bit .NET 4.0.30319.42000)

Starting: WhateverProject.UnitTests
Finished: WhateverProject.UnitTests
=== TEST EXECUTION SUMMARY ===
WhateverProject.UnitTests Total: 79, Errors: 0, Failed: 0, Skipped: 0, Time: 8.398s

However when I am using OpenCover.Console.exe to execute the tests and measure the coverage, I am getting DirectoryNotFoundException:

C:\WhateverProject>OpenCover.Console.exe -output:".\opencover.xml" -register:user -mergeoutput -target:".\packages\xunit.runner.cons

It looks like OpenCover.Console.exe is looking for the source code to calculate the unit test coverage. Try delete All EntityFramework.*.pdb files.
