The schema defines two elements:

Let's get started making a full-blown GUI app that will frontend this calculator service. Open
the .NET framework console, and execute the following command, supplying the location of
your WSDL:
C:\Program Files\Microsoft Visual Studio 8\VC>wsdl
/out:C:/oreilly/soacookbook/code/chapters/interop/dotNetClient/Calcul
atorProxy.cs http://localhost:8080/CalculatorApp/
CalculatorWSService?wsdl
Here you just indicate that you want the
wsdl
utility to write the C# file to the specified loca-
tion on the filesystem, using the provided WSDL URL. The utility options always come first,
each indicated by a / character, followed by the option name, a colon, and the value. The
WSDL location always comes last, after the options list.
The code the WSDL tool generates looks like that shown in
Example 12-8
,
though I've cut
some unnecessary parts to keep it short and added a little formatting for readability.
