If you're interested in building reliable, secure and efficient Web Services, Microsoft's Patterns and Practices site just released the
Web Service Software Factory that will be a great starting point for people building Web Services using ASP.NET. The Web Service Software Factory includes documentation covering Service Oriented Architecture (SOA) fundamentals, message design, exception handling and migration to Windows Communication Framework (WCF). It also includes "Guidance Packages" that provides VS.NET 2005 wizards and other tools to generate code that follows best practices. If you're interested in practicing the process of building SOAs, several hands-on labs are also included. Although WCF isn't covered in this release (other than planning for migrating to WCF), it is planned for the future.
