title: Using TFS API on a non-developer system
body: <p>I have written a program that makes use of TFS api to synchronize bugs between TFS and some other system. </p>
  
  <p>This program runs as a windows service on a non-developer machine so that it can work in the background.</p>
  
  <p>It seems that the program expects the system to contain several team foundation assemblies in the GAC (e.g. Microsoft.TeamFoundation.WorkItemTracking.Proxy.dll location). Unfortunately, there aren't such assemblies.</p>
  
  <p>Copying the assemblies in the program directory doesn't work. Though the program is starting I immediately receive a 'MissingMethodException'.</p>
  
  <p>Does anybody know if this environment requires a regular installation of some VS/TFS component and maybe a client access license? </p>
