Kirk Allen Evans talks about his adventures in discussing with several at PDC one of my past favorite topics: distributed transactions. I have renewed interest in this, and in particular Enterprise Services again, as I will be speaking on the new System.Transactions namespace in .NET 2.0 at next week's Code Camp 4.
Kirk also talks about how in-depth discussions with the most knowledgeable people are again one of the best values of attending conferences like PDC. I couldn't attend unfortunately, but I know from my experience at TechEd earlier this year (when I got a chance to speak with the System.Transactions team), such discussions are priceless!
