Answer 1

When you get the add new association dialog there is an option selected called "Add foreign key properties to the 'your entity name' Entity". Make sure you deselect this option.

You'll also probably need to set up Referential Constraint in the associations properties panel - this is what EF uses to use the association in your navigation properties.
