Do you have some solution like Data Contract Resolver?

as you can see in https://learn.microsoft.com/en-us/archive/msdn-magazine/2011/february/msdn-magazine-data-contract-inheritance-known-types-and-the-generic-resolver#data-contract-resolvers

when WCF try to resolve inheritance in data contract, we have to define Data Contract Resolver like below

public abstract class DataContractResolver {
  protected DataContractResolver();
  
  public abstract bool TryResolveType(
    Type type,Type declaredType,
    DataContractResolver knownTypeResolver, 
    out XmlDictionaryString typeName,
    out XmlDictionaryString typeNamespace);
  public abstract Type ResolveName(
    string typeName,string typeNamespace, 
    Type declaredType,
    DataContractResolver knownTypeResolver);
}

How to get same behavior in protobuf-net.Grpc?

@mgravell Did you have any idea?

thanks

Normally in protobuf-net , we never store explicit type information: we just store a numeric tag; the way we build the serializer currently means that you'd really need to register the known tags in advance (via the "include" functionality, usually via [ProtoInclude(...)] at compile time, although it can also be specified at runtime).

What you are describing here sounds more like "any" (a protobuf feature). I haven't had need to implement good "any" support in protobuf-net, but that's something we could do - however, due to how protobuf objects work, this is more about arbitrary message types, not inheritance.

What would help here is: what is the scenario you're trying to solve?

I exactly want to resolve some problem like #300

many thanks to response

@mgravell I think protobuf-net need some practice like WCF to support inheritance in clean way :)

I think this feature must be add to https://github.com/protobuf-net/protobuf-net

@mgravell Did you can help me to where this feature must be implemented?

thanks
