Asynchronous methods - callback method is never called

[C# Programming]

Hi.

I have this console based Asynchronous VS project that works fine.
And then i have a remoting project which also works fine. I want to edit the remoting project so it is non-blocking, using asynchronous calls.

I´ve tried different examples, but I cant get it to work. None of them seems to call my callback method back.

Here is the relevant snippets:

The remote object:


....
public class MultiContainer : MarshalByRefObject, IMultiContainer
{
public string GetClientsList()
{
Thread.Sleep(1000);
return Program.ServerForm.GetClientsList();
}
....



The client which accesses the remote object with asyn call:


namespace Client
{
public partial class Form1 : Form
{
Server.IMultiContainer mc;
private delegate string Delegate();

public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
mc = new Server.MultiContainer();
Delegate del = new Delegate(mc.GetClientsList);
AsyncCallback callback = new AsyncCallback(Callback);
del.BeginInvoke(callback, null);
}

private void Callback(IAsyncResult ar)
{
//this callback method is never called...
Delegate del = (Delegate)((AsyncResult)ar).AsyncDelegate;
richTextBox1.Text = del.EndInvoke(ar);
}
...



Been sitting with this problem for hours, hope you can help!
