title: EntityFramework 7 (EF7) Migrations. DbContext and StartUp Project are in different assemblies
body: <p>I'm trying to use migrations in EF7 with entityframework.commands. But my DbContext is in different assembly with Start-up project (asp.net mvc is an start-up project and Core.Implementation has a DbContex).</p>
  
  <p><strong>dnx . ef migration add MyMigration -c MyContext</strong></p>
  
  <p><em>System.InvalidOperationException: No DbContext named 'MyContext' was found.</em></p>
  
  <p>I've tried to use namespace to point to other assembly but it didn't work either. Is it possible at all? Or I just have to put my context in assembly where ef7 command is?</p>
