Eric Johnson's Blog IT Architect - My ramblings on work, technology, & life in general

A while back I attended a Microsoft internal briefing moderated by Raj Pai.  This was a very informative presentation and I am grateful to Jeff Brand for getting me involved with the call.   Here is an overview of some of things discussed during the presentation.  Sorry about the delay in posting this information, but I just got my blog and have a lot of back blogging to do. :)

I used this information to create my C# 2.0 Whidbey presentation that I presented to my user group (CRINETA).  If you are a member of CRINETA you can download it from our website.  Otherwise you can download it from my personal website.
