title: PresentationFramework DLL could not be loaded
body: <p>I am running a <strong>TeamCity</strong> build which is running <strong>FXCop</strong> Analysis.<br>
  Getting the following error:</p>
  
  <pre><code>[INFO] 2&gt;Project : error : CA0058 : The referenced assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' could not be found. 
  </code></pre>
  
  <p>Now, this error is coming on only one of the machines, and he build is running fine on all remaining ones.</p>
  
  <p>I've checked the following (same on all the machines)</p>
  
  <ol>
  <li>Checked that the assembly is present in GAC</li>
  <li>Verified that Visual Studio 2010 and FXCop 10.0 are present on all machines and verified the configuration.</li>
  </ol>
  
  <p>Any idea?</p>
