The book 'Advanced MVVM' has a quick review posted by Laurent Duveau.
Sometimes I am asked if books exists on MVVM (Model-View-ViewModel). So you have this little book I
read a while ago, Advanced MVVM by Josh Smith. I like this kind of book which go straight to the
real content (only 52 pages).
The author chose to illustrate MVVM with a game instead of a business
application, it can seems weird at first but anyway... Also the book covers MVVM
implemented with WPF, not Silverlight, but this is just a question of view and
the pattern is more than that, so that should not disturb you from learning MVVM
even if you only do Silverlight apps. What you read in the book can be applied
to Silverlight as well. If you want something specific with Silverlight you can
start with this link:
