Hi,I was asked this question in an interview and wasn't exactly sure how you would implement it. I was given a brief overview of the situation. multiple wpf applications that connect ot a wcf service and a wcf service that connects to a db.The told me the data in thew db is continually changing (and not by the WPF apps). So they asked me how I would keep the wpf apps provided with the latest data. So I am assuming there is another app e.g. windows service that is continually polling the data?Its basically I guess very similar in style to a trading application.Any thoughts would be most welcome. Thanks.
