First of all, I would like to thank Tim Kent for the constant input he's given across all of the chapters; this book couldn't have been delivered without his help. In addition, Martyn Bullerwell has helped out massively by writing a great chapter on the API, which I know took a while, and personally I think adds a great deal of value to the book.

A huge thanks also goes to Neil Dobner for the many hours he unselfishly put in on the BizTalk section. Neil carried this in his own time, in the middle of delivering a large project for one of our clients, so he put himself out to help, and it's very much appreciated.

I would also like to thank Sacha Tomey and David Morrison for the input they've provided, as well as Ian Ahern for writing the foreword.

In addition, I must also thank the technical reviewers, Valentino Vranken, Marc Delisle, and Shashank Pawar. Their comments and suggestions have helped improve the quality of the book, and have resulted in additional content that makes the book broader.

Finally I would like to thank the Packt team for the guidance given throughout the whole process. Thank you to Kerry George, Neha Mallik, Leena Purkait, and Sakina Kaydawala.
