Accessing Application Web Services (Visual Basic)
The My.WebServices object provides an instance of each Web service referenced by the current project. Each instance is instantiated on demand. You can access these Web services through the properties of the My.WebServices object. The name of the property is the same as the name of the Web service that the property accesses. Any class that inherits from SoapHttpClientProtocol is a Web service.
The following table lists possible ways to access Web services referenced by an application.
