Is anyone familiar with these books or the technology availabled in the original book verses what is currently available? I have the first edition of the book and I was wondering if it made any sense to buy the lastest edition. I do notice that the first edition isn't very helpful in setting up IIS7. That isn't a problem currently since I have VS2010. But some later chapters I may not be able to do because of this.

Are there significant differences in the books and technology? I've bought books by the same authors before that the info was exactly identical with just a few changes.

Thanks!
