This course provides a realistic, hands-on coverage of developing distributed applications using .NET and C#. It covers Web services in depth and introduces .NET Remoting. Web services are an evolving series of standards that enable programs on various computers to communicate with other programs on similar or disparate computers transparently over the Internet. .NET remoting enables a .NET client to interact with a .NET component in a different application domain, which may be hosted on a different computer. 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.

For students pursuing MCTS certification, the course provides helpful preparation for Exam 70-529: Microsoft .NET Framework 2.0—Distributed Application Development.

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 two chapters discuss important technologies at the foundation of ASP.NET Web services, including XML serialization and SOAP.

Chapter 8 provides a practical discussion of data access using Web services. The next chapter covers 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. The course concludes with an introduction to .NET Remoting.
