json.net - Serializing/deserializing derived objects in SignalR -

i using signalr 1.1 .net clients. have single method in hub accepts object of basemessage class , broadcasts clients:

public void sendmessage(basemessage message) {     clients.all.broadcastmessage(message); } 

clients pass derived messages method:

_hub.invoke("sendmessage", new errormessage("some error")).wait(); 

the client has single message handler:

_hub.on<basemessage>("broadcastmessage", onmessagereceived); 

i've specified typenamehandling.all serializer settings @ application startup:

var settings = new jsonserializersettings { typenamehandling = typenamehandling.all}; var serializer = new jsonnetserializer(settings); globalhost.dependencyresolver.register(typeof(ijsonserializer), () => serializer); 

but when client sends derived message, server receives base message.

how should configure serializer able receive derived messages?

note: can serialization/deserialization manually , pass strings server, causes double serialization.

signalr not supporting scenario require json payload contain information derived type , assembly. see sample. adding type information in payload not play browsers. suggest create individual hub methods handle each of derived types.
