This is a terrible book, obviously rushed to print that is all over the map. It tries (and fails) to be a book on user interface, WPF, Expression Blend, elementary C# programming, and most bizarrely how to tell a story (to give an example of how they filled this book they spend one page summarizing Aristole's De Poetica). The examples of using Blend itself are so convoluted and poorly explained that I couldn't figure out how to do half of them, and since Blend is a relatively radical change from standard Microsoft Designer and Programmer UI's walking through the steps more clearly would have been the minimum one would have expected. All the screenshots included are so small (and full screen) so you can't even make out what they are talking about. As I am not a graphics designer, this may have some appeal to that crowd (though I can't imagine why), this is not the book to use to learn Expression Blend from a programmers perspective. The code in here is also TERRIBLE (for example they create XML by creating XML strings one at a time and then appending that to a file?? If you are going to create XML with a string at least use the StringBuilder class but really this should have been done with XMLWriter or at worst the XmlDocument.) Avoid this book at all costs.
