A new Application Block for Enterprise Library is out already. Version 2 of the Updater Application Block allows you to easily build apps which automatically detect and download updates. Clever stuff.

Incidentally, check out the excellent Enterprise Library Webcasts, available on Ron Jacob's website. When EntLib was released in January, I initially spent very many hours spelunking around in the codebase, which really isn't the best way to get to grips with this library. There's an awful lot going on behind the scenes, but the number of publically exposed methods are generally small, so the Enterprise Library remains easy to use despite its complexity. These webcasts and the slides have provided me with a good overview - now I just need a shiny new project on which to use it in anger :-)
