Applied SOAP: Implementing .NET XML Web Services
This book takes the reader from the architecture of .NET to real-world techniques they can use in their own Internet applications.  The reader is introduced to .NET and Web Services and explores (in detail) issues surrounding the fielding of successful Web Services.  Practical guidelines as well as solutions are provided that the rader may use in their own projects.  Some of the issues involve lack of specific guidance in the SOAP specification, while others transcend SOAP and involve issues Internet developers have grappled with since the inception of the World Wide Web.  At this time, this book has no competition.
