Question

I\'m using the new EF code first to one project of mine, and i\'m getting a weird error, my mode is:

abstract class Member
{
   public virtual int MemberId;
  ..         


        

Answer 1

I just tested it and tables of derived types in TPC (table per concrete type) inheritance don't have PK defined as identity in EF 4.1 RC.
