JetBrains Rider 2018.1 xUnit not work

Hi,

I run some tests written in F# in a test project. I receive the following  error:

  Transition failed: Transition from state <HandShake> on event <remote::.ProtocolVersion>.
  Cause: System.InvalidOperationException: Test-cases are missing for the selected tests. Rebuild the project and try again.
