Sorry but you must not have read much of the text on this website at all.

You need to look into WCF Callbacks. That would be the best way to do it, in my opinion. To expand on pseudorandom's post, the people on this site are not here to spoon feed. We will help with a specific problem, but it's up to you to do the work first and then come when you can't get a specific part to work properly.

Daniweb is all about the learning experience, it is not a lazy man's code library.

EDIT: XAML would be used on WPF and XML is used to create things like the WCF bindings and configuration in the app.config file. You will need to learn what these settings do otherwise you could be scratching your head for a long time when something goes wrong as the error messages in WCF aren't always "correct"
