J# and out parameters

I came across another peculiar scenario for J#.
We all believe that out parameters would not have to be initlialized since they are expected to return a value from the calling method. But then again we have to think how its implemented in J#. Ironically J# doesnt have a good idea about out parameters and guess it uses it as a ref

Hello world for IAsyncResult

Here is a hello world for IAsyncResult.
I was wondering - does this internally spawn its own thread ? Need some info as to how to catch exceptions thrown from this ?

Any help would be appreciated.

using System;

namespace IAsyncTest
{
	class Program
	{
		public delegate void AsyncTask();
		
		[STAThread]
		static void Main(string[] args)
		{
			Task t = new Task();
			AsyncTask asyncTask = new AsyncTask(t.DoTask);
			IAsyncResult ar = asyncTask.BeginInvoke(new AsyncCallback(t.Done),null);
			Console.ReadLine();
		}
	}

	public class Task
	{
		public void DoTask()
		{
			Console.WriteLine("Start Sleep");
			System.Threading.Thread.Sleep(10000);
			Console.WriteLine("End Sleep");	
		}

		/// <summary>
		/// IAsyncCallback Method
		/// </summary>
		/// <param name="ar"></param>
		public void Done(IAsyncResult ar)
		{
			Console.WriteLine("Done");
		}
	}
}
