Craig McMurtry, Marc Mercuri, Nigel Watling and Matt Winkler work directly with the Windows Communication Foundation development team to tell the world about the technology. As such, the authors have exclusive access to the very designers and developers that are producing the technology, as well as to early releases thereof. That access provides insights into features and application of the technology that others do not have, as well as knowledge of how the technology will evolve, and familiarity with best practices that are only just being formulated by the testing teams. More importantly, the authors devote their time to assisting enterprises and software vendors to adopt the Windows Communication Foundation, and that yields them significant insights into how others see the technology, how they wish to apply it, and the challenges they face. The new material proposed for the second edition derives from their experiences since the first edition went to press.
