Table isn't showing up as a FK dependency (dotted line assoc) when added to .edmx?

I have a TableA that includes a TableBId dependency. When I try to delete and re-include TableB my .edmx is still not showing an association between TableA and TableB. My db is FK relationthip in the db looks fine. 开发者_开发技巧

Any ideas? When I try to add the Navigation property to the table it won't let me select the "Select Association" the property as I thought I could manually add the association within the .edmx.

Unless you've really customized the entity, delete both and right click and add again from the database.
