Standard WebService calls

Modern definitions of webservice generally tend to be restfull-style HTTP requests, but they still encounter the time code written by their predecessors.

We prefer to encapsulate the code to invoke instead of the service reference. Please see:

Annotations for Service.asmx Services

The above can not be verified.

The request method (which removes the namespace of the service returned by the server) is submitted as a post
