Do you avoid using Thread.Sleep in your Silverlight application?

Calling Thread.Sleep on your Silverlight application causes the UI thread to sleep. That means the application is not responsive.

If you want to delay something, you can use a storyboard.

Thread.Sleep(5000); 

this.Dispatcher.BeginInvoke(new Action(() => 
  { 
    // Try to reconnect in the background 
    Connect.Execute(null); 
  }));

Storyboard sb = new Storyboard() { Duration = TimeSpan.FromSeconds(5) }; 
sb.Completed += (ds, de) => this.Dispatcher.BeginInvoke(new Action(() => 
  {
    // Try to reconnect in the background 
    Connect.Execute(null);
  }));
sb.Begin();
