The Developer?s Guide to Windows SharePoint Services 3.0 teaches developers how to build solutions that leverage the Windows SharePoint Services 3.0 (WSS v3) platform. Many developers are not yet familiar with this platform and its capabilities, so the fi rst few chapters focus on the out-of-the-box experience and how to secure solutions built on top of it. From there, the book explores some of the key aspects of the WSS v3 platform and how to leverage them for building applications. Throughout the book, practical programming solutions using real-world examples are used to illustrate the possibilities of SharePoint and to teach developers how to build their own applications. Some application components covered include Features, Site Defi nitions, Web Services, Web Parts, Events, and Workflows. The book also teaches how to migrate from 2.0 to 3.0 and to work with the object model and built-in WSS Web Services in various settings. Developers who want to usurp the fundamental capabilities of WSS v3 rather than building those facilities themselves will fi nd everything they need. The book doesn?t attempt to cover the capabilities of Microsoft Offi ce Server System 2007 (MOSS), but MOSS is based entirely on WSS v3 so all the examples found in this book can also be used in that environment too. In fact, everything covered in this book equally applies to WSS v3 and MOSS. While this book attempts to bring developers from the ground up, any Web-based .NET programming experience will prove helpful in understanding the concepts presented within. The C# language is used exclusively in the text but there are comparable VB.NET code listings on the CD-ROM.
