title: Using EF 4.4 and not 5.0 with VS2012
body: <p>We move some projects from VS2010 to VS2012 but still using .NET 4.0 and <strong>not</strong> .NET 4.5</p>
  
  <p>When I add an new EDMX, VS2012 use EF 5.0 but I'd like continue to use the version 4.x it's the first point.</p>
  
  <p>Second point the version 5.0, inherit from DbContext and not ObjectContext like version 4.x. With the version 5.0 I don't see any way to pass the connection string as parameter.</p>
  
  <p>How can I use version 4.x in VS2012, with the same EDMX designer behavior ?</p>
  
  <p>Thanks,</p>
