How can RuntimeTypeModel be used to bind ProtoInclude to a type in protobuf-net?

Question

As I understand it, RuntimeTypeModel allows you to associate ProtoInclude with a type, which is useful for cases when the type declaration cannot be changed. But it’s hard for me to understand how this is actually done.

Is there an example?

Thanks.

AddSubType() used to specify derived types along with their identifier; e.g. ( full code ):

  static RuntimeTypeModel CreateModel() { var model = TypeModel.Create(); model[typeof(NotInvolved)].Add(1, "D"); model[typeof(SomeBase)] .Add(1, "A") .AddSubType(2, typeof(SomeDerived)) .AddSubType(3, typeof(AnotherDerived)); model[typeof(SomeDerived)].Add(1, "B"); model[typeof(AnotherDerived)].Add(1, "C"); model[typeof(AlsoNotInvolved)].Add(1, "E"); return model; } 

The configuration of the model above is of the entire type at runtime, but you can also mix and match between automatic (through properties) and explicit (through code).
