Changing Inherited Types in Entity Framework

by

No. The EF inheritance does not support this scenario. The best way to create a Student for an existing Person is to use a stored procedure.

Please note that this is not a stored procedure that is wired up to the Student entity through mappings, but a separate one that can be called explicitly from code. Ideally it would be a SP that takes a PersonID as a parameter, inserts a new row into the Student table using that PersonID, and then returns a complete Student so that it can be used immidiately.
