SOA (Service Oriented Architecture) is the next big step in evolution for Web services. This book is the first to educate people about SOA, and to introduce them to the technologies that they can use today, prior to the release of Indigo. It will introduce them to a new architecture and will help them realize why Web services are such a big deal (beyond today's popular but very limiting focus on using Web services primarily for RPC method calls). This book will contain a mix of theory combined with ample C# code samples that will show the reader how to implement SOA solutions using a wonderful mix of technologies. It will teach people about SOA today while preparing them for SOA tomorrow. This is applicable to all systems running Windows 2 or higher.
