I use MVC 4 Internet Application with VS 2012 and Entity (5.0) Framework Database First..
I created my database with relationships..
I create ADO.NET Entity Data Model.. And I can see all relationships (one-to-one, one-to-many, many-to-many)..
I want to create my controller and views with "mvc controller with read/write actions and views using entity framework".. There is no problem with One-to-Many and One-to-One..
How about Many-to-Many??
All problems, which are something like that, are about the ViewModels..
