Invoking signalr hub with a type that has derived types

Hello,

I am facing an issue when i try to invoke a method at SignalR Server from SignalR client.

Background:

Hub.Invoke("MethodToBeCalled", MessageType).Wait();

The MessageType is defined as

public class MessageType
{
  primitive type prop1;
  primitive type prop2;
  List<BaseAction> Actions {get;set;}
}

BaseAction is a base class for two derived types; RunningAction and RowingAction.

Issue:
When i pass the CLR object of MessageType to the Hub.Invoke all the type information are lost when they reach the SignalRHub so basically i can't tell apart RunningAction from RowingAction because JSON Serialization just considers them all as BaseAction(BaseType).

Could anyone suggest if there is a way to workaround this problem?

Thanks in advance:)

What I have tried:

I have tried the

Hub.JsonSerializer.TypeNameHandling = TypeNameHandling.All;

at the client before the connection is started. But when i do this it always fails with Server 503.

No change when trying the same at the SignalR(OWIN) server side:

var myHubJsonSetting = new JsonSerializerSettings()
        {
	TypeNameHandling = TypeNameHandling.All
	};

var serializer = JsonSerializer.Create(myHubJsonSetting);

_signalR = 
WebApp.Start(
 GetStartupOptions(),
 builder =>
 {
   builder.UseCors(CorsOptions.AllowAll);
   GlobalHost.DependencyResolver.Register(typeof(JsonSerializer), () => serializer);
   builder.MapSignalR(
		serviceName,
		new HubConfiguration
		{
		  EnableJSONP = false,
		  EnableDetailedErrors = _detailedErrors,
		  EnableJavaScriptProxies = true
		});
   builder.RunSignalR();					
  });
