Linq to Entities, Table per Type and Nullable Foreign Key Relationships.

Answer 1

Hi Crafty, I looked at your example project. Try updating the AssociationMapping node in the Mapping section of your EDMX file to include a condition to allow for nulls.

e.g.

<AssociationSetMapping>
  ...
  <Condition ColumnName="" IsNull="false"/>
</AssociationSetMapping>

Cheers,
