title: missing pdb file
body: <p>I'm debugging my app on a wince7 device. </p>
  
  <p>After couple minutes I'm getting an error: "No symbols are loaded for any call stack frame. The source code cannot be displayed."</p>
  
  <p>I noticed on the modules list that I have 1 dll that is missing pdb file. Its name is System.Drawing.dll . 
  I noticed that the module added to the module list after some thread (that I'm not creating and I don't know who) is created. </p>
  
  <p>I'm getting the error only after the thread is running.</p>
  
  <p>Anyone know where can I find the needed pdb file? (I have already tried to repair the .net compact framework)</p>
  
  <p>How can I find out where the thread is starting? (I can't find it in the code)</p>
  
  <p>What should I do next?</p>
  
  <p>Please help</p>
