title: Add function import functionality seems to be broken in EF6
body: <p>I am trying to import a function into my entity model. I am running VS 2012, using Entity Framework 6 with the according tools and yet no stored procedures or function names appear under the relevant drop down in the "Add Function Import" dialog. </p>
  
  <p>Does anyone else have this issue? If so, does anyone have a solution?</p>
