Ok, so I have the service reference in my .NET project. And yes I know that you now have access to proxy classes.
But in the past, I am used to doing this via an HttpWebRequest object using NVP, but never tried using the WSDL and sending a SOAP request this way.
I'm not quite sure which object to use to send the request. Not sure where to start here. I've looked at the docs but seen no good examples out there for .NET and PayPal.
Other than a WSDL vs. sending an HttpWebRequest via a NVP API and querystring params, I really do not understand if there's a difference in how you send the request. It's all just over Http so can't you use HttpWebRequest also over a SOAP API (using WSDL)?
