title: Entity Framework - Already Defined
body: <p>I have a problem with an EDMX file which I've never encountered before. Seemingly randomly when the site is running or I'm debugging, the EF will bomb out and complain that everything is re-defined. I have to restart the app pool and re-attach the debugger every time, then start again from where I left off, after which it works again until the next time it bombs out.</p>
  
  <p>I've already recreated the EDMX with a different name, hence MyAppEntities*<em>1</em>*</p>
  
  <p>The error is:</p>
