Hi everybody,

I'm trying to create a very simple remoting application and I'm trying to do
it using "Marshal By Value" (using MarshalByRef it works fine).

the problem is: I get this exception:

Trying to create a proxy to an unbound type.
  at System.Runtime.Remoting.RemotingServices.Unmarshal(Type classToProxy,
String url, Object data)
  at System.Activator.GetObject(Type type, String url, Object state)
  at System.Activator.GetObject(Type type, String url)
  at RemotableClientNamespace.RemotableClient.Main(String[] args) in
c:\........

Does anyone can help?
thank you in advance

Here is the code:

Host code:

using RemotableTypeNamespace;
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;

namespace remoteHOST
{
class remoteHostClass
{
 [STAThread]
 static void Main(string[] args)
 {
  ChannelServices.RegisterChannel(new TcpChannel(7567));
  WellKnownServiceTypeEntry info_service_to_register = new
WellKnownServiceTypeEntry(typeof(RemoteClass),"RemoteClass",
WellKnownObjectMode.SingleCall);
  string result = RemotingConfiguration.ApplicationName = "Remote Server";
  RemotingConfiguration.RegisterWellKnownServiceType(info_service_to_register);
  Console.WriteLine("{0}: listening for requests.\n\nPress Enter to
exit...", result);
  Console.ReadLine();
 }
}
}

Servant code:

using System;
using System.Threading;
using System.Diagnostics;
using System.Windows.Forms;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace RemotableTypeNamespace
{
[Serializable]
public class RemoteClass : ISerializable
{
 int x;

 public RemoteClass() { this.x=1; }
 public int GetX()  { Console.WriteLine("Will return ... {0}", this.x);
return this.x; }
 void ISerializable.GetObjectData(SerializationInfo info, StreamingContext
context) { info.AddValue("x", x);  }
}

}

client code

namespace RemotableClientNamespace
{
class RemotableClient
{
 [STAThread]
 static void Main(string[] args)
 {
  TcpChannel c = new TcpChannel();
  ChannelServices.RegisterChannel(c);
  RemoteClass  remoteObject;

  try
  {
   remoteObject = (RemoteClass)Activator.GetObject(typeof(RemoteClass),
"http://localhost:7567/RemoteClass");
   remoteObject.GetX();
  }
  catch(Exception e)
  {
   ChannelServices.UnregisterChannel(c);
   Console.WriteLine(e.Message);
   Console.WriteLine(e.StackTrace);
  }
 }
}
}
