Web Services Using C# and ASP.NET

Current Version: 2.0

This course provides a realistic, hands-on, comprehensive coverage of developing Web services using ASP.NET and C#. Web services are a series of standards progressively being developed, that enable programs on various computers to communicate with other programs on similar or disparate computers transparently over the Internet. This course teaches in detail the skills needed to program Web services using ASP.NET. It also examines the fundamentals of SOAP and WSDL essential for creating interoperable Web services. The course is current to .NET 2.0 and Visual Studio 2005, with coverage of new features such as the WS-I Basic Profile 1.1, SOAP 1.2, event pattern for calling Web services asynchronously, and more. It also includes an introduction to Web Service Enhancements (WSE) 3.0.

The first chapter introduces Web services and Service Oriented Architecture (SOA). The baseline Web service specifications of XML, SOAP, WSDL and UDDI are outlined.

Chapter 2 covers the fundamentals of SOAP and WSDL. Web services are developed using the .NET Framework SDK. Chapter 3 covers the details of how to create and debug ASP.NET Web services using Visual Studio 2005.

Chapter 4 shows how to create clients for Web services using an SDK tool and using Visual Studio 2005. Sophisticated topics, such as state management, caching and transactions in Web services are covered in Chapter 5. The next three chapters discuss important technologies at the foundation of ASP.NET Web services, including XML serialization, SOAP and WSDL.

Chapter 9 provides a practical discussion of data access using Web services. The course concludes with an introduction to Web service security using WSE 3.0, which provides implementation of advanced Web service protocols such as WS-Security, WS-Trust and WS-Policy. WSE 3.0 also provides a diagnostic message tracing tool, which is used in the course to trace SOAP packets, providing insight into the anatomy of Web services.

Knowledge of the .NET Framework using C# and an understanding of the fundamentals of XML. Some experience in ASP.NET is advantageous.
