title: VS Team Services gives false error on continuous integration 'This version control host is unsupported'
body: <p>hoping someone has seen this before.</p>
  
  <p>When I try to enable continuous integration in Visual Studio, using Visual Studio Team Services, I get the following error:
  "<strong>This version control host is unsupported. Repositories must be hosted on VSTS or GigHub</strong>." This error gets zero results in google.</p>
  
  <p>As you can see in the screenshot, the solution IS hosted by VSTS. </p>

  <p>Explaining the screen shot:</p>
  
  <ol>
  <li>Section 1 in the pic is the pop-up that appears after clicking 'Configure Continuous Integration' in the VS2017 status bar.</li>
  <li>Section 2 is my VS team explorer window. </li>
  <li>The grey boxes are the company website '<em>mycompany</em>'.</li>
  </ol>
  
  <p>Additional facts:</p>
  
  <ol>
  <li>The VSTS account is owned by admin@<em>mycompany</em>.com, but my dev account, jason@quantumland.com, has full contributor permissions to the project. I get the same error whether red box 1 above has my personal account selected or admin@<em>mycompany</em>.com</li>
  <li>The current loaded solution is the basic starter '.NET Core Web application' in VS2017 Community edition. No authentication selected, no changes to the auto-generated code. </li>
  <li>I can build and run the solution locally, check in the solution to VSTS, see the code in the VSTS repository, publish to Azure web app, etc. Everything seems to be working but this.</li>
  </ol>
  
  <p>Appreciate any help. My best guess is that my security permissions are wrong in VSTS, but both accounts are members of the 'admin team' group, and admin@<em>mycompany</em>.com is the creator/owner of the VSTS account and repository, so I don't see how.</p>
