Query: This book is 99% crap.

I have 2 bookshelves of bargain .net books. This is by far the worst on the whole collection.I was expecting a book on component building. What I got was a walkthrough of building a clunky enterprise application. For component building, I reccommend the Apress! Class design Handbook as a starting point.Despite the inappropriate title, I read on and found poor practice after poor practice. If I were tasked with maintaining the resulting application, I would schedule a re-write from scratch.For a better insight about modern real world n-tier and component development, I recommend any of Rockford Lhotka's Business Objects books, especially the newer ones.
