Not at present. The reason the delegate does not accept the delegate is because it aims to statically compile the model — MethodInfo is suitable for this, but delegates: not much. However, the factory method you supply can take a serialization context, which can contain any objects you need.
I might think of a factory default method — that sounds possible; I need one of the arguments to be a type, but that is not a problem.
Will it be possible to set the factory factory MethodInfo default value, which can (if required) use the type and serialization context?
