title: WIX custom action debugging doesn't work
body: <p>I have tried to debug my custom action.
  I put Debugger.Break() into custom action cs.
  When I build custom action it creates this files: </p>
  
  <pre><code>myCustomAction.dll
  myCustomAction.CA.dll
  myCustomAction.pdb
  </code></pre>
  
  <p>In wix project I reference myCustomAction.CA.dll inside binary tags (not myCustomAction.dll).
  Since there doesn't exists myCustomAction.CA.pdb is this the reason that debugging doesn't work?
  I have tried also with messagebox and attach to process, when message box is shown.
  But i get the following message: Cannot find or open the PDB file.</p>
  
  <p>What I'm doing wrong? I have wix 3.5 version and visual studio 2010.</p>
