body: <p>When using workspace.GetLocalItemForServerItem() I am getting an exception</p>
  
  <pre><code>An unhandled exception of type 'Microsoft.TeamFoundation.VersionControl.Client.ItemNotMappedException' occurred in Microsoft.TeamFoundation.VersionControl.Client.dll
  </code></pre>
  
  <p>with inner exception </p>
  
  <pre><code>There is no working folder mapping for $/MyProject/MyProjectSubDir/teambuild/tfsbuild.proj.

  <p>It works perfectly well on one machine but not on another.</p>
  
  <p>Any ideas?</p>
