I'll be speaking on this coming Sunday at the SoCal Code Camp at Cal State Fullerton.
My session is at 9:00 AM on Sunday and is titled Bridging the Desktop/Web Divide with WPF and Silverlight. I'm hoping to demo (still working on my code) a simple application I built in WPF and show how easy it is to port it to XBAP and Silverlight with a few potential extras (exporting to XPS and a very short demo of ADO.Net Data Services which is the data provider).
My fellow Avanaut Elmer Morales will also be presenting on Sunday afternoon on Building Stunning Sites with SharePoint 2007. Elmer has been building SharePoint 2007 sites well before the product was released and from what I've seen of his presentation so far it should be great.
I'll probably miss the Saturday presentations since I still have some work to do on my own :)
So see you at Code Camp!
