title: Debugging error when editing code
body: <p>Occasionally I get this strange error when debugging code. It occurs when I change something in code while debugging.</p>
  
  <p>This isn't really linked to the framework, as this was happening in different versions so far.</p>
  
  <p><em>Translated from german:</em></p>
  
  <pre><code>Error 1 The sourcefile "C:\Users\xxxx\AppData\Local\Temp\8\.NETFramework,
  Version=v4.5.1.AssemblyAttributes.cs" 
  could not be opened("Unknown Error").   folderOfProjectFile
  </code></pre>
  
  <p>The whole directory "8" isn't existant in <code>appdata\local</code>
  there is only "4"</p>
  
  <p>Additional Info:  </p>
  
  <ul>
  <li>Visual Studio Premium 2013, though I bellieve it happened in 2010 too.  </li>
  <li>Terminalserver running 2008 RC2 DataCenter x64</li>
  </ul>
  
  <p>There isn't much Google offers when searching for this errormessage. Mostly because my translation probably isn't exactly the correct one.</p>
  
  <p>Here is the original exception</p>
  
  <pre><code>Fehler  3   Die Quelldatei "C:\Users\XXXX\AppData\Local\Temp\5\.NETFramework,
  Version=v4.5.1.AssemblyAttributes.cs" 
  konnte nicht geöffnet werden ("Unbekannter Fehler ").     folderOfProjectfile
  </code></pre>
  
  <p>Does anyone know what could cause this problem?</p>
