title: TFS Build Fails
body: <p>We run TFS 2008 and Visual Studio 2010B2 (as with any Beta, errors are predominant).</p>
  
  <p>Below are the errors given (from the build log):</p>
  
  <pre>
  Task "DeleteWorkspaceTask" 
  DeleteWorkspaceTask 
  TeamFoundationServerUrl="http://dev-svr:8080/" 
  BuildUri="vstfs:///Build/Build/1679" 
  Name="**ALICE_3_**" 
  DeleteLocalItems=True

  <p>Any input would be appreciated, as this area of development isn't my forte.</p>
