Chapter 19. Introduction to XML Web Services

Microsoft .NET XML Web services are supported by Microsoft Internet Information Service (IIS) versions 5.0 and later. It’s important that IIS be already installed on a machine before the .NET installation is performed: the .NET installer recognizes that IIS is installed and establishes the bindings that allow Microsoft ASP.NET and XML Web services to function. If IIS is installed later, the .NET Framework must be removed and reinstalled.

The XML Web service support in .NET is provided by ASP.NET, a component of .NET that is outside the scope of this book. ASP.NET is used by IIS to invoke XML Web services; however, the details and features of ASP.NET aren’t required to write XML Web services.
