    Very informative and helpful in understanding the flow of control in an asynchronous event handler. The message pump, the processing of those messages, and the completion of a message loop is how I understand this "void" return notion better. Oh, and thank you for sharing the Silverlight group panel example. ASP.NET can use thread pool threads, but from  what I have read, Silverlight, WPF, Windows Forms, and Windows Store apps map an application design model with a threading model that only permits that single thread that created the UI to update that UI. An event handler that returns a Task would have prevented partial print-outs because all of the requested data had not yet populated that panel control.  An async marked event handler that returns a Task would rule have an await expression: the control flow would execute in a more sequential order, despite the pausing point and continuations.

    Many Thanks
