title: Visual Studio 2012 Add controller with Context fails when connectionstring configSource in place
body: <p>Working with VS 2012 + MVC4 + EF5 trying to add controller with Context fails when connectionstring configSource in place with Error :</p>
  
  <p>"Unable to retrieve metadata for MvcTestApp.Models.DummyClass. Unable to open configSource file 'connections.config'.</p>
  
  <p>BTW: The path is correct the application actually runs correctly.</p>
  
  <p>Does Visual Studio 2012 EF5 support connectionStrings configSource to be in a separated file at design time ? or no way during development !!!</p>
  
  <p>Thanks for your feedback.</p>
