title: Team Foundation Server Change Source Control Invalid Status
body: <p>I have a new laptop because the old one is crashed.
  On the old laptop I have a Visual Studio solution that is connected to Team Foundation Server and there were a lot of changed made before I could do a check in.</p>
  
  <p>Luckily I made a backup of the complete folder structure inclusive my changes.</p>
  
  <p>Now on my new laptop I installed VS2013 and copied the solution to my harddrive (E: disk). When I open the solution, all the projects are loaded correctly, but there is no connection to TFS.</p>
  
  <p>When I look at "Change Source Control" all the projects have a Invalid status.
  I tried to set the workspace correctly but nothing worked so far.</p>
