Perhaps the problem is that I've always developed LAN systems and I'm really a newbie in .NET and Web Services.
I try to be more specific: Let's say that I create a class (VFP 8 SP1) named USER that has 2 properties ID and NAME and a method LOGIN. With this scenario I'm able to instantiate an object and work with it during the session started in the system.
In the other hand I can create a Web Service named USER that exposes to web consumers the service named LOGIN, then I'm able to "call some distributed functions" and not deal with real objects.
I apologize for my very basic way of thinking but definitely I don't understand how to handle objects through Web Services.
