I saw on Amazon that Vittorio, Garrett, and Caleb's new CardSpace book, "Understanding Windows CardSpace" has shipped.
As Vittorio and I were teammates when our respective CS book projects began, some people asked me if there were any competitive juices flowing. Not at all, the reality is that I had signed the deal with my publisher for my book after finishing WCF Hands On! and before hearing from Vittorio he was working on a book on the subject. Rather than being competitive, the hope was the end results would be complementary. From looking at Amazon, it looks like that may just be the case, which is greatness.
Congrats to Vittorio, Garrett, and Caleb all on this latest addition. Hopefully this encourages more folks to write books on the subject.
