WebClientAsyncResult Class
Assembly: System.Web.Services (in system.web.services.dll)
When you call the BeginMyMethodName method, where MyMethodName is the synchronous version of the method, on an XML Web service proxy class, an instance of the WebClientAsyncResult is returned. Following the standard asynchronous design pattern, that instance of WebClientAsyncResult must later be passed to EndMyMethodName to complete the asynchronous method call.
For details on calling XML Web services asynchronously, see Communicating with XML Web Services Asynchronously.
