           Summary: Remoting problem: Object type System.Int64 cannot be
                    converted to target type System.Int32

The serverside was tested with mono 1.9 on debian lenny, mono 2.2 with the mono
vmware image, Windows XP32bit and Windows Vista 64bit with the Microsoft .Net
Framework.
The client-side was running Windows XP 32bit and Windows Vista 64bit with the
Microsoft .Net Framework.

The problem occures only if the client is running on Windows Vista 64bit and
the server on Mono 32bit.

So I think its a problem with mono running 32bit and the client is running
64bit. 

Here is an example of the server:
=========================

using System;
using System.Collections.Generic;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

namespace RemotingServer
{
    public class Program
    {
        static void Main(string[] args)
        {
            Dictionary<string, object> dict = new Dictionary<string, object>();
            dict["name"] = "ServerChannel";
            dict["port"] = 5001;
            dict["typeFilterLevel"] = "Full";

            // create the server channel
            TcpChannel server_channel = new TcpChannel(dict, null, null);

            ChannelServices.RegisterChannel(server_channel, false);

            RemotingServices.Marshal(new SessionFactory(), "SessionFactory");

            Console.WriteLine("Press key to exit the application ...");
            Console.ReadLine();
        }
    }

    public class SessionFactory : MarshalByRefObject
    {
        public override object InitializeLifetimeService()
        {
            return null;
        }

        public SessionObject Login()
        {
            return new SessionObject();
        }
    }

    public class SessionObject : MarshalByRefObject
    {
        protected ApplicationClient m_client = null;

        public ApplicationClient ApplicationClient
        {
            get { return m_client; }
            set { m_client = value; }
        }
    }

    public class ApplicationClient : MarshalByRefObject
    {
        public ApplicationClient()
        {
            // den ClientChannel registrieren
            ChannelServices.RegisterChannel(new TcpChannel(), false);
        }

        public SessionObject Login(string hostname)
        {
            SessionFactory factory =
(SessionFactory)Activator.GetObject(typeof(SessionFactory),
string.Format("tcp://{0}:5001/SessionFactory", hostname));

            SessionObject session = factory.Login();

            if (session != null)
                session.ApplicationClient = this;

            return session;
        }
    }
}


Here is an example of the client:
=========================

using System;

using RemotingServer;

namespace RemotingClient
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                ApplicationClient client = new ApplicationClient();
                client.Login("monoserver");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.StackTrace);
            }

            Console.WriteLine("Press key to exit the application ...");
            Console.ReadLine();
        }
    }
}




And here is the exception stacktrace that occurs when assigning the
ApplicationClient instance to the server object.

if (session != null)
  session.ApplicationClient = this;



stacktrace:
