title: How do I associate test methods to test cases?
body: <p>I am unable to associate test methods to test cases in the Test Explorer (the "Associate to Test Case" option is greyed out), or via MTM, or the VSTS website.  I simply cannot find a way to associate tests to the test cases for automated testing.</p>
  
  <p>I am using .NET core app 1.1, ASP.NET using MSTest (though I have tried Xunit as well, to no avail).  Even a basic test case that always passes cannot be associated.</p>
  
  <p>In MTM, I have created a test plan that has the Automation Status set to "Plan".</p>
  
  <p>In VSTS, I have a project using a Git repository, in which I have a CI build created that successfully discovers, runs and reports the tests.</p>
  
  <p>I cannot find where to associate these specific tests to test runs.  How may I accomplish this?</p>
