A dependent property in a ReferentialConstraint is mapped to a store-generated column

Question

I get this error when writing to the database:

A dependent property in a ReferentialConstraint is mapped to a store-generated column. Column: \'Paym

Answer 1

I had the same problem. Based on the answers provided here I was able to track it and solve it, but I had a strange issue described below - it might help somebody in the future.

On my dependent tables, the foreign Key columns have been set to StoreGeneratedPattern="Identity". I had to change it to "None". Unfortunately, doing so inside designer didn't work at all.

I looked in the designer-generated XML (SSDL) and these properties were still there so I removed them manually. I also had to fix the columns on the database (remove the Identity(1,1) from CREATE TABLE SQL)

After that, the problem went away.
