I am having the same problems as other people here regarding getting the "Try It Out" examples to work. The code in the chapters is giving a lot of errors. It is impossible to learn how to do something if you cannot do it from the examples.
Very poor book, I am going to bin it and get a better one with code downloads that don't drive me insane.

I'm trying to follow this book but it's tricky. They always switch between C:\websites\wroxunited and C:\begASPNET2\wroxunitedcs. Also, we supposed to try to create the wrox site on our own but it doesnt clearly specify to use the \chapters examples or something the actually site that you downloaded. Are we supposed to be working from 3 sites? 1 for the chapters, 1 for the downloaded application, and 1 for our own creation??? Please excuse my newbiness!

bao72,
  I think the idea is to use the "begin" folder for the chapter your on. The "end" folder is what your final work should look like and the "WroxUnited" folder is the final product. If your having trouble running the code for individual chapters try looking at the "end" folder for that chapter. You will probably find the mistake you made or one that isn't documented. Most errors that aren't documented should be easy enough to figure out on your own. If you stuck use google for the errors or post it here.
