It sounds like you have the model working and mapping already?
But you just need to remove the extra navigation property?
If you want to remove the navigation property it is pretty simple (although you can't do it the standard EF designer).
You simply open your EDMX file in an XML editor (easy enough inside VS) and delete the unwanted <NavigationProperty .../>
from the Customer Entity.
This way the relationship still exists in the Model, but in the class you can only go from Store.TopCustomer
you can't go the other way.
Hope this helps
