title: Entity Framework 6.4.4 (.NET 4.7.2) - No connection string named
body: <p>Good day,</p>
  <p>I've created a C# .NET 4.7.2 class library project which integrates EF6.  When the parent project makes any call to the DLL for db access, the above exception is thrown.</p>
  <p>A common solution is to include a reference to EF in the parent project and to copy the connection string element from the class library's app config file.  This indeed works, but is not ideal.  I really envision all of these settings encapsulated within the DLL.</p>
  <p>Anyone have a work-around?</p>
  <p>Thanks.</p>
