title: Working with both Visual Studio 2008 and 2013 using TFS?
body: <p>Some of my colleagues use Visual Studio 2008, while others, including myself are on 2013.  Almost all of the solutions in Team Foundation Server were created using Visual Studio 2008.</p>
  
  <p>The problem arises when I open a Visual Studio 2008 solution.  It forces me to perform a one-way upgrade, thus checking out the solution file.  At that point, the users on Visual Studio 2008 are unable to open the solution.  </p>
  
  <p>Is there any workaround to opening source controlled solution files in a newer version while still allowing my colleagues on 2008 to work with the solution?  Are we using TFS incorrectly?  Should we not be checking in the solution and project files?</p>
  
  <p>Thanks!</p>
