[gentoo-user] Mono/C#: cannot listen with TcpChannel

[Mike Mazur]

Hi,

Having trouble with TcpChannel throwing an exception:

$ cat temp_test.cs
using System;
using System.Net;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class MainClass
{
	public static void Main()
	{
            try
            {
                TcpChannel ch = new TcpChannel(8895);
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception while attempting to
listen on TCP port 8895.");
                throw (ex);
            }
	}
}
$ mcs -r:System.Runtime.Remoting.dll temp_test.cs
temp_test.cs(13,28): warning CS0219: The variable `ch' is assigned but
its value is never used
Compilation succeeded - 1 warning(s)
$ mono temp_test.exe
Exception while attempting to listen on TCP port 8895.

I also tried the example at
http://www.gotmono.com/docs/remoting/introduction.html but this
exhibits the same problem.

I'm new to Mono development, so I'm not too familiar with all its
libraries and/or components. Could I be missing something that's in
portage?

Thanks in advance,
Mike
