Finished reading Essential Silverlight 2 (Up-to-Date) by Christian Wenz. I've posted about the look and feel of the "Up-to-Date" concept when I got the book. To that aspect I can only add that it was actually more comfortable to read than I've anticipated. The binder doesn't stand in the way and probably is sturdier than paperback or even hardcover.
I was mostly interested in Part 3: Programming Silverlight with .NET. But to my surprise it dealt with embedding Silverlight into ASP.NET pages rather than actual programming of Silverlight apps.
Anyway I got my share of excitement about the technology and feel pretty comfortable to start actually doing some stuff with it after reading this book.
Verdict: succeeds at getting reader excited about Silverlight 2 and stops right there
P.S.: This review refers to the book with "Update 1" (Beta 1) applied.
