Web method functionality
ASP.NET makes it possible to map traditional methods to Web Service operations through the System.Web.Services.WebMethod attribute.
In a nutshell, the WebMethod infrastructure takes care of dispatching incoming SOAP requests to the appropriate class and method (based on either the request element's name or the SOAPAction header, configurable through SoapDocumentService.RoutingStyle) and serializing/deserializing the XML message into the common language runtime (CLR) objects, including the translation of .NET-style exceptions into SOAP Fault elements.
In addition, the infrastructure automatically generates a WSDL definition that describes the WebMethods using XML Schema types and WSDL constructs (http://localhost/geometry/geometry.asmx?wsdl). The System.Web.Services namespace contains a slew of additional attributes used to control dispatching as well as the XML Schema and WSDL mapping
