My article on the Microsoft Application Blocksis now live on the asp.netPRO site. Unfortunately for some, you have to be a subscriber to access it. It will be in the next print mag that comes out as well.
The article covers the blocks at a high level, then drills down into the DAAB and the UIP blocks. I have other articles on the site for the CMAB blockand have one on the EMAB coming out soon online as well. These latter two are not locked to subscribers only.
