I originally had a table with an Integer Primary Key that was Auto Generated (Is Identity = true) on the server.  The business object property _PrimaryKeyFields contains the field "Id".

I added a new field Guid (UniqueIdentifier) to the table and changed the primary key to it instead of the Id field.  When I build the partial class with the Business Object Mapper, the _PrimaryKeyFields property does not contain any field names.

What am I doing wrong???
