Question

Is it posible to define a compound foreign primary key without defining scalar properties?

public class A 
{
  public virtual int AID { get; set; }
}

public class B
{
  public virtual int BID { get; set; }
}

public class CompoundKeyClass
{
  public virtual A AObject { get; set; }
  public virtual B BObject { get; set; }
}

How can I make properties AObject and BObject the compound PK of CompoundKeyClass without defining the scalar ID properties of for A and B types using the FluentAPI?

Answer 1

You can’t. Both AID and BID must be in your CompoundKeyClass mapped as complex primary key and each of them must be mapped as foreign key to related table.
