ServiceNow integration with .NET
You're in luck! You can specify a URL parameter in your WSDL URL to drive elementFormDefault.
Add this to your WSDL URL:
elementFormDefault=qualified
...here's what a full URL would look like:
https://<instance name>.service-now.com/<table name>.do?WSDL&elementFormDefault=qualified
You can validate this by simply loading up the WSDL in your browser and looking for this XML snippet at the top:
<xsd:schema elementFormDefault="qualified"
