Does protobuf-net support [DataMember(Order=0)]?

Question

I am using protobuf-net with WCF, and finding that data members with Order = 0 are not showing up on the client. Here is my data contract - ObjectId is always Guid.Empty on

Answer 1

Odd - I would have expected it to error with that. Protobuf key numbers are always positive, so 0 is indeed not valid for protobuf-net. Hence I would expect it to throw! For this reason, it. Is also possible to specify an offset to apply to WCF keys (intended primarily for use with proxy types). This can be done via ProtoContractAttribute (directly, or in a "partial class" if using proxy generation), or can probably (I haven't checked) be applied at runtime via RuntimeTypeModel.
