Community Convergence LIII

Welcome to the fifty-third edition of Community Convergence. Here at Microsoft the C# team is still busy polishing C# 4.0 so that is shines and glistens. Below I provide some links to recent articles of interest by C# team developers, other Microsoft employees, and community members. Included is a fun video by Kirill Osenkov on his Live Geometry library, and a Jason Zander link to the new Windows XP to Windows 7 Reference application.
