Steve Porter and myself are driving up to Charlotte tonight to present on Silverlight at the Developers Guild meeting. Steve will be giving an overview of Silverlight features and development, and of course I will be deconstructing my newest Silverlight game - Gem Blaster!
If you remember Popper!, this is the next generation of that game engine, upgraded to work with the newer Alpha 1.1 Refresh, and with better graphics and gameplay. You can also go directly here to play the game: http://www.mindfusioncorp.com/gemblaster/
EDIT: The game has been moved to the Wintellect servers at: http://www.wintellect.com/gemblaster/
I am also working on getting the source code published to CodePlex, but it has taken a while due to my very busy work schedule.
