title: Azure DevOps 'Run Only Impact Tests' doesn't work with XUnit Tests?
body: <p>I have an ASP.net Web API project (.NET Framework v4.6.2) where I have written unit test cases using XUnit. </p>
  
  <p>I have created a build pipeline in Azure DevOps with '<em>Run only impacted tests</em>' set to <em>checked</em>. Also, my Visual Studio test version is set to *2.** in my test assemblies.</p>
  
  <p>I have tried to run my mock tests (No data driven test cases) to check that only impacted test run but all the tests run. </p>
  
  <p>I had hard luck finding the solution for It. Can anyone know how to do it right?</p>
  
  <p>I have read this article and and done setting accordingly, but failed.</p>
