[Mono-list] Remoting under XSP problem

[Hendy Sumanto]

We are having problem getting remoting on mono running under XSP.
This is the way we are starting up the remoting. It works fine not running under XSP.

using System;
using System.Text;
using System.Globalization;
using System.Reflection;
using System.IO;
using System.Collections;
using System.Text.RegularExpressions;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.ServiceProcess;

using ExcelInterface;


namespace bridge_service
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpChannel channel = new TcpChannel(8081);
            ChannelServices.RegisterChannel(channel);

            RemotingConfiguration.RegisterWellKnownServiceType(typeof(ExcelApplication), "ExcelHelper",
                WellKnownObjectMode.Singleton);
            System.Console.WriteLine("Press the enter key to exit excel server.");
            System.Console.ReadLine();
        }
    }
}


And in the client we are using this to try to access the remote service but it always failed. 

                // Create the application
                ExcelApplication xl = (ExcelApplication)Activator.GetObject(
                        typeof(ExcelApplication),
                        "tcp://localhost:8081/ExcelHelper");
                xl.Visible = false;

The error message we got:

Server Error in '/ETS' Application

I tried to disable shadow copying through Web.Config by adding
<hostingEnvironment shadowCopyBinAssemblies="false" /> 
but still getting the same error message as above.

Any idea about this?

Thank you.
