I'm studying the Ajax in chapter 10.
in the TryItOut in page 352, we use HTML controls, and according to the book, and I quote: "you can see that the code you are going to write really

One more thing, in page 352, there is this quote: "By referencing the service in the master page, it becomes available to all pages based on that master.
needed to run this service."
