Popular author Jeffrey Hasan will draw you into the service-oriented architecture (SOA) mindset, in preparation for the release of Indigo-the new Web services protocol and infrastructure support for SOA. Now is the time to consider SOA and to think about how to architect applications using XML messages and loosely-coupled services. With this book, you can get a head start on building SOA applications, using the .NET Framework combined with the Web Services Enhancements (WSE) 2.0 toolkit. Web services are hot - and with the release of WSE 2.0, Microsoft developers now have a toolkit that makes it easy to implement industry-standard specifications for building secure, reliable Web services. This book provides deep insight into the newest release of the WSE toolkit: blending theory with ample C# code samples, and directly teaching you how to implement SOA solutions that are based on specifications such as WS-Security, WS-Policy, and WS-Addressing. Most .NET-based Web services are simply containers for limited RPC-style methods. This book will show you how to shift your development paradigm to create Web services that process sophisticated XML messages within a secure, service-oriented, loosely-coupled architecture. Jeff gives you the practical information you need today, while at the same time preparing you for what you will need tomorrow.
