I'm using Visual Studio 2005 Beta1. A windows application consumes my
HelloWorld web service. But i can't call the event based model in the client
application.

I can't do this in the windows client application:

void btnClick(.................)
{
  service.HelloWorldCompleted+=new HelloWorldCompletedEventHandler
(this.HelloWorldCompleted);
}

The problem is i can't call the serviceMethod's Completed event from client.

Any idea?
