WPF Internals book recommendation
===

Most of the WPF books are oriented towards practical examples of how to use that technology. Those are mostly the HOW rather than WHY books. They are fine but a lot of times I find my self not completely understanding the logic behind some WPF features even though I use them daily. In order to become really good at something a deeper knowledge is required. So I was wondering is there some kind of WPF internals book that has deeper explanations of the whole technology (layout system, rendering, bindings...). That Dr.WPF guy had great explanations in his blog and MSDN forum posts but unfortunately he is no longer updating his blog. Some kind of book written in that style would be great but I am not aware of any?
