> Hello Kpix,
> I have another improvement request for you. I defined a base class Domain=
Object, which already defines an ID (note that PascalCaseMUnderScore is a c=
ustom FieldAccessor so I can use strong typing instead of strings):
> =09public class DomainObjectInt : DomainObject<int>
> =09{
> =09=09[Id(0, Name =3D "ID", Column =3D "ID", TypeType =3D typeof(Int32), =
UnsavedValue =3D "0",
> =09=09=09AccessType =3D typeof(PascalCaseMUnderScore))]
> =09=09[Generator(1, Class =3D "identity")]
> =09=09public override int ID
> =09=09{
> =09=09=09get { return base.ID; }
> =09=09}
> =09}
> Now when I want to define inheritance hierarchies I run into trouble:
> =09[Class(0, NameType =3D typeof(Operation), Table =3D "[Operation]", Laz=
y =3D false)]
> =09[Discriminator(1, Column =3D "Discriminator")]
> =09public abstract class Operation : DomainObjectInt, IOperation
> =09{
> =09}
> I'd like to place the discriminator right at the top with the class defin=
ition. However, it's only valid on property, indexer or field. The workarou=
nd is to place it e.g. on top of the first member variable but that's misle=
ading when someone looks at the code.
> Is there a reason why I couldn't place that attribute on top of the class=
?
> Thanks, Christoph
