In there, I can see the Public Class declaration. I see the structure which causes all this trouble. I see how the WCF mechanism handles all this and sends the data to the Web Service. But, I cannot see where to initialize all those properties of the structure.

Say that you have a web service that looks like this in .NET (c# I'm afraid):

public class WebService1 : System.Web.Services.WebService
    {
          [WebMethod]
        public Something GetSomething()
        {
            return new Something();
        }

        [WebMethod]
        public bool TakeSomething(Something s)
        {
            return true;
        }
    }
    public class Something
    {
        public string A { get; set; }
        public int B { get; set; }
        public SomethingElse C { get; set; }
    }
    public class SomethingElse
    {
        public string Name { get; set; }
    }

If you use WCF to reference this (the fact that it originates from .NET code is irrelevant) then you could use something like:

ServiceReference1.WebService1SoapClient sc = new ServiceReference1.WebService1SoapClient();
            ServiceReference1.Something s = new ServiceReference1.Something();
            ServiceReference1.SomethingElse se = new ServiceReference1.SomethingElse();
            se.Name = "Fred";
            s.C = se;
            sc.TakeSomething(new ServiceReference1.Something());

(Names could make more sense but it should demonstrate the basics....)
