[Mono-dev] 1.2.4 -> 1.2.6 broke remoting?

[Jay L. T. Cornwall]

Hi,

I have a simple remoting example that works fine on Ubuntu Gutsy 7.10 
(with Mono 1.2.4) but fails on 8.04 (with Mono 1.2.6 and with 
source-built 1.9.1). This is the stripped down server:

HttpServerChannel channel = new HttpServerChannel(52938);
ChannelServices.RegisterChannel(channel, false);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteInterfaceFactory), 
"RemoteInterfaceFactory.soap", WellKnownObjectMode.Singleton);

This is the client:

HttpClientChannel channel = new HttpClientChannel();
ChannelServices.RegisterChannel(channel, false);
IRemoteInterfaceFactory factory = 
(IRemoteInterfaceFactory)Activator.GetObject(typeof(IRemoteInterfaceFactory), 
"http://localhost:52938/RemoteInterfaceFactory.soap");
IRemoteInterface remoteInterface = factory.Create();

The remote interface is shared in a DLL between the client and server:

(In shared .dll)
public interface IRemoteInterfaceFactory {
   IRemoteInterface Create();
}

(In server .exe)
public class RemoteInterfaceFactory : MarshalByRefObject, 
IRemoteInterfaceFactory {
   public IRemoteInterface Create() {
     return new RemoteInterface();
   }
}

On Mono 1.2.6 and 1.9.1 I receive this exception once the 
factory.Create() method is called:

Unhandled Exception: 
System.Runtime.Serialization.SerializationException: The object with ID 
2 could not be resolved

(System.IO.Stream serializationStream, 
System.Runtime.Remoting.Messaging.HeaderHandler handler) [0x00000]
...

However, the complete RPC system works fine on 1.2.4. Has a technique 
that I've used been obsoleted?

Thanks,
