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()
               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

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 some libraries? I'm
running Mono on Gentoo Linux.

Thanks in advance,
