title: How to change debugger settings for debugging individual unit tests from VS 2015 Test Explorer
body: <p>Test Explorer allows to run tests under debugger and I use it quite often for debugging single tests. However debugger settings used in this case are different from that set for the test project and prevent efficient debugging. I would like to limit debugging to managed mode only for UWP class library while debugger starts always in mixed native/managed mode. This prevents any debugging as .NET Core does not support mixed mode debugging. I work on VS 2015.</p>
  
  <p>After checking and testing all possible settings I have failed to switch debugging mode from mixed to managed only. Any ideas?</p>
  
  <p><strong>Not solved:</strong> cleanup and rebuild of MEF cache resolved problem for a short time. </p>
  
  <p>Debugging fails with error msg <em>Unable to attach to CoreCLR. Interop debugging is not supported</em></p>
