Whenever a new version of Silverlight is released, I start examining its features from two perspectives: how would my current (and planned) LOB applications benefit from using these new features, and what cool new things can I build to entertain my children.

This article will guide you through the process of creating a doodling application (you know, for kids ;)), while covering some of the most visible (or not) new features, coming with Silverlight 4. But this is not just about new features, it’s about how they are prepared and served.
