Web services using C# and ASP.NET

Beskrivelse:
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 concludes with an exploration of Web services security and the emerging Microsoft Global XML Web Services Architecture (GXA).

Målgruppe:
Programmers needing to integrate Web Services.

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