# Many simple webservice scripts can not handle more complex webservices like the MSDN ContentService for example, so I wrote this script from the ground up and modeled it on the .NET SDK’s WSDL.EXE. It supports Basic Profile 1.1 and can generate proxy instances for simple ASMX services and more complicated multi-schema services like the MSDN/TechNet Publishing System (MTPS) Content Service.
# No need for the .NET 2.0 SDK, just PowerShell 
# Auto discovery of all referenced schema 
# No need to point it at page.asmx?wsdl any more, just the asmx 
# Validation against WS-I Basic Profile 1.1
# By default, it asks for credentials. If targetting a public webservice, specify the -Anonymous switch.
