Out with the old and in with the new... the HackingSilverlight Code Browser is a reference tool for code snippets so that I can not have to remember how todo things. for that matter the tool doesn't really show you how it just has a bunch of code that is tagged and searchable.

Composite Surface/WPF/Silverlight 3/Silverlight 3 OOB project for fun and for demo-ing going from Silverlight to WPF and the use or resources in both kinds of projects and then again going from WPF to Surface allowing users to show the differences between all 3.5 environments.
