hi friends , i wanna know the reason, why in silverlight we are calling wcf service method like this

SampleWebServiceSoapClient client = new SampleWebServiceSoapClient();  

 client.HelloWorldCompleted +=   new EventHandler<HelloWorldCompletedEventArgs>( client_HelloWorldCompleted );

client.HelloWorldAsync();

private void client_HelloWorldCompleted( object sender, HelloWorldCompletedEventArgs e ) 

  {  }

Hi,

Calls to serve side are async for does not stop a UI thread of Silverlight application.
