Web Services Training Overview
This course provides a realistic, hands-on, comprehensive coverage of developing Web services using ASP.NET and VB.NET. 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. 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 first chapter introduces Web services, including evolution, motivation, backbones, and reasons to embrace Web services. Chapter 2 exposes the anatomy of a Web service through hands-on exploration and tracing of a simple Web service, examining HTTP, XML, 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 .NET. Chapter 4 shows how to create clients for Web services, both manually and using ASP.NET. and consume the same in various clients. Sophisticated topics, such as state management, caching and transactions in Web services are covered in Chapter 5. The next four chapters discuss important technologies at the foundation of ASP.NET Web services, including XML serialization, SOAP, WSDL and UDDI. The .NET classes for manipulating WSDL files are explored, and the UDDI .NET SDK is introduced.
The course concludes with an exploration of Web services security and the emerging Microsoft Global XML Web Services Architecture (GXA). The discussion includes the various security issues and technologies in Web services such as Basic HTTP, HTTPS, (SSL 3.0), XML Signature, XML Encryption, XML Key Management Specification (XKMS), Security Assertion Markup Language (SAML) and WS-Security.
