For those of you that missed Deeper in .NET, and didn't think my live blogging was enough, you can find links to presentation and code downloads at the WI-INETA site here. I highly recommend the slides for The Science of a Great UI and The Scaling Habits of ASP.NET Applications. The information presented in those two presentations were truly unique. The LINQ presentations were good overviews of the technologies and new language changes to support them, and are worth downloading to review, but can also be found easily in numerous books, white papers and MSDN articles.
