Interesting, do you have to run though all registered classes that are sub-classes of the base class and cast them checking for null?

Honestly I haven't tried this I would have assumed that D still gives you
the real type when using reflection but have you tried it?

Unfortunately the only why to get a value of field by reflection requires the static type to be known. When serializing through a base class reference the static type is lost. Therefore it's required to register the subclass, one way or another.
