Web Services Using C# and ASP.NET (VS2008)

Course Description

This course provides a realistic, hands-on, comprehensive coverage of developing Web services using ASP.NET and C#. 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 course is current to .NET 3.5 and Visual Studio 2008, with coverage of newer 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 Windows Communication Foundation (WCF), Microsoft’s modern unified framework for creating distributed applications.
