I will be speaking at NNUG Trondheim next week about how one can go about creating games using managed code with focus on Xna and Silverlight. The user group meeting is a cooperation with Javabin.
If you happen to be in Trondheim on the 29th of October, stop by for a great evening with Anders Nordås talk about patterns and myself for the gaming section.
You can sign up and read more over at NNUG.
