title: Strange Exception when using Entity Framework with SQLCE
body: <p>I have used before EF 4 and SQLCE with no such problem.</p>
  
  <p>While I have my assembly containing the edmx file and the context self tracking template and in another assembly the self tracking entities, I keep this strange compile error but the project compiles successfully...</p>
  
  <pre><code>Error   1   Error 175: The specified store provider cannot be found in the configuration, or is not valid.
  </code></pre>
  
  <p>This just dont go away....but the program runs.</p>
  
  <p>Any idea?</p>
