I have two tables parent and child.

If I make a foreign key on child that points to the primary key of parent, and then make an entity diagram, the relationship is shown correctly.

If I make the foreign key point to a different column, the relationship is not shown.

I have tried adding indexes to the column, but it does not have an effect.

The database is sqlite, but I am not sure if that has an effect since its all hidden behind ADO.net.

How do I get the relationship to work correctly?
