title: How can I reference TeamFoundation assemblies in my project?
body: <p>I need to reference Team Foundation assemblies in my project but I cannot. </p>
  
  <p>When looking for Microsoft.TeamFoundation.* in the GAC I cannot find any assemblies.
  Then I browse to C:\windows\assembly and here I find the assemblies that I need.
  When I select all or one of the assemblies to create a reference nothing happens. The dialog 'blinks' and returns focus to the top of the list. The reference is not created?! I have tried this with other assemblies in this directory and I cannot make a reference to any of them.</p>
  
  <p>I restarted VS and tried again. No luck. So how do I reference these Dlls? I have TFS installed on this machine.</p>
  
  <p>Thanks..</p>
