Am găsit următoarele cărți foarte utile:
Windows Presentation Foundation Unleashed - Adam Nathan
You mention you already have this book, however I wanted to give my opinion on it. It is a great book for the newcomer - it is printed in full color which is a great help for visualizing both xaml and concepts for WPF.
Essential Windows Presentation Foundation - Chris Anderson
This is also another great book for the newcomer. While it is not printed in color, it does give a great insight into how wpf works.
Pro wpf in C# 2008 - Matthew Macdonald
This is a great reference book - one that sits on my desk and is constantly referred too. However, I didn't feel is was as newbie friendly as the other two books above. This is the most recently released book (at the time of this posting), and has been updated for VS2008. This is useful, as there are some changes with the versions of WPF. I believe there is a VB.NET version available.
Programming wpf - Chris Sells & Ian Griffiths
Another great book - I wish this was available when I was first learning the framework.
Application = Code + Markup - Charles Petzold
This was the very first wpf I purchased. It is not very newbie friendly, and I wouldn't recommend it for a first-time-wpf'er. The fact that Xaml is not introduced until page 457 makes learning the technology for the real world very difficult. That said, this book is invaluable if you really want to understand how things work at a very deep level (which is also important to get the most of the framework.
Singura carte pe care o voi evita în totalitate este:
Professional wpf Programming - Chris Andrade et al.
While the content was Ok in this book, I just found the other books to be much clearer and delve to a much deeper level.
Sper că acest lucru vă ajută! wpf are o curbă abruptă de învățare, dar odată ce o "obții", programarea UI poate deveni "distractivă"!
