The desire to do this directly has already been proposed, and is on my list to look at, but: treating types with inbuilt serialisation (int etc) as part of inheritance has some technical issues that are not very interesting. My recommendation here is to use an abstract base class with generic concrete implementation, and an "include" attribute on the base-type to cite each of the expected types at runtime - Foo, Foo etc. DynamicType would also be a consideration here, but without a few minor tweaks I don't think this works immediately for dictionary. It could do, though.
