I am using Entity Designer to create a database first model. Now I want to create a foreign key relationship between ProductId and ProductId (see below). I looked at the "add new association" but I cannot connect the two items. Can someone more experienced tell me how to accomplish this?

According to Relationships/Associations with the EF Designer, the steps to create a foreign key association are:

1. Right-click an empty area of the design surface, point to Add New, and select Association….
2. Fill in the settings for the association in the Add Association dialog.

...being sure to check the Add foreign key properties to the Entity checkbox when filling in the relationship details.
