Data Binding in Windows Presentation Foundation

Hopefully this is just part of the pains associated with trying to use beta software, but I can't find good documentation on data binding in Windows Presentation Foundation. I have found multiple examples of how easy it is to bind to an Xml data source but I have never had a need to bind to Xml data. I guess if I was writing an Rss centric app, it would be really useful. I am trying to figure out how to just bind to business objects or a database. I can tell from the Xml examples I have found, that data binding is more powerful than ever. It just looks a little complicated when you have multiple ways of writing declarative data binding (verbose and shortcut). I have just now started my journey of learning the WinFX world. I have a Windows Communication Foundation (WCF) app started but have run into troubles there as well. (I will explain that in a future blog post) So far, I am very excited about the next generation of Windows and .Net development. It will be very interesting to see what types of applications come out of these new technologies after the dust settles.
