I`m reading this book in my workplace. The book is giving a good coverage of the framework and the ways one can use it. The problem is the book relies heavily on examples and the code for these examples is obsolete. It seems Microsoft has drawn back some of the generic classes that appear in this book. I`m currently using the Microsoft examples supplied with the SDK documentation. But theses examples relies on onfiguration files which is quite different than the DIY approach the book has taken. So it`s really hard combining this with reading the book. My suggestion is: Wait for a release of the book that is updated for the current WCF / Indigo version.
