Answer 1

Try to remove foreign property column from Entity set using entity model design it will solve your problem

For example

We have two tables one is customer and other one is order, using entity model design we added association between customers and orders when we do this Ado.net entity framework i will add navigation properties to both below tables.

Like Customer.Orders - Here order is list Order.Customer

One - Many relation.

So we need to remove property from with name CustomerId[Foreign key column] from Order entity set.

Answer 2

My experience with EF v1 is similar to yours. When the EDM is generated incorrectly and you can't work around the issue, you have to manually edit the EDM. EF v.Next (Entity Framework v4 I believe) will support "Code Only" Entity Data Models, and the EDM designer is supposed to be much better. One or the other improvement should make our lives easier. Until then...
