A book for wcf 4.0

Question

Hi, I need some book where I can learn how to extend WCF 4.0 (ie. write some cusom behavior, custom factory etc.)

Answer 1

i use this book http://www.amazon.co.uk/Professional-WCF-Communication-Foundation-Programmer/dp/0470563141 and its been very well written IMO

Answer 2

Programming WCF Services, Third Edition by Juval Lowry is the book that you want. I used the first edition for getting up to speed with WCF 3.0, and there was no better guide to understanding the architecture of WCF with a view to extending it. In the third edition, the book has been updated to cover WCF 4.0.
