I recently bought Paul Yao & David Durant’s Compact Framework Programming Book (which is also available on-line) to help me ramp up to writing something for my smartphone. It looks like a very comprehensive book (my wife likened it to a phonebook in size), and if it is like most of the other titles from the Addison-Wesley “Developer” series it should be good. The only thing I don’t like about it thus far - their advocacy of hungarian notation (something I am not such a fan of). I guess old windows API programmers never die.
