BeginSend Socket Test Mon

BeginSendSocketTest.cs

/*
I have a piece of .NET code that uses Asynchronous sockets that I want to cross
compile and run on Mono, however, when I attempt to run it, the AsyncCallback for
the BeginSend never gets called. I've boiled down the problem to a very simple
example. The example does not ever hit the callback, I have tried the following
configurations:

OS: Ubuntu 10.10 (Maverick Meerkat)
Mono 2.8.2 using Nathan Bridgewater's install shell script
Mono 2.10.2 using Nathan Bridgewater's updated shell script
Both using MonoDevelop F5 and compiling in MonoDevelop but running in the console

The behavior of the mono versions is slightly different:
- Using 2.8: The console hangs, never invokes the callback and never exits
- Using 2.10: The console exits but does not invoke the callback

In both cases, the Socket error code reports Success.

Note: This is a client, not a server.

using System;
using System.Net.Sockets;

namespace BeginSendSocketTest
{
	class MainClass
	{
		static ManualResetEvent wh;

		public static void Main (string[] args)
		{
			wh = new ManualResetEvent(false);
			var packet = new byte[4];
			var socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
			socket.Connect("localhost",11211);
			SocketError errorCode;
			socket.BeginSend(packet,0,packet.Length,SocketFlags.None,out errorCode,OnDataSent,socket);
			Console.WriteLine("status: " + errorCode.ToString());
			wh.WaitOne();
			wh.Dispose();
		}
		
		public static void OnDataSent(IAsyncResult result)
		{
			try
			{
				Console.WriteLine("Callback has been invoked.");
				var socket = (Socket)result.AsyncState;
				var sent  = socket.EndSend(result);
				Console.WriteLine(sent + "bytes sent");
			}
			catch (Exception e)
			{
				Console.WriteLine("Exception from EndSend");
			}
			wh.Set();
		}
	}
}

Just wanted to try to unify flow behavior across versions…
