Meanwhile, my progress through the book for 70-562 has stalled at chapter 6. I got through chapters 1-5 in about a week, but then last week, I got distracted from this due to a sudden burst of job interviews (three in a row). I also just wanted to take my time getting through the ASP.NET AJAX material, since I found it to be very interesting, and I wasn’t that familiar with it.
I bought a cheap used copy of Dino Esposito’s “Introducing Microsoft ASP.NET AJAX” book from Amazon, to supplement the overview in the 70-562 book. It looks like this will be a good place to start. I’m not sure now when I’ll be getting back to studying for 70-562, though, due to these side trips. I’d still like to take the test next month, but we’ll see if I have the time to do that or not.
