Type Hier

Answer 1

This is how I resolved my inheritance problem:

public static class DataObjectBaseExtension
{
    public static void DefaultMap(this ClassMap DDL) where T : IUserAuditable 
    {
        DDL.Map(p => p.AddedUser).Column("AddedUser");
        DDL.Map(p => p.UpdatedUser).Column("UpdatedUser");
    }
}

You can then add this to your superclass map constructor:

internal class PatientMap : ClassMap
{
    public PatientMap()
    {
        Id(p => p.GUID).Column("GUID");
        Map(p => p.LocalIdentifier).Not.Nullable();
        Map(p => p.DateOfBirth).Not.Nullable();
        References(p => p.Sex).Column("RVSexGUID");
        References(p => p.Ethnicity).Column("RVEthnicityGUID");

        this.DefaultMap();
    }


}
