Have you ever thought of invoking your Web Services
dynamically without having to generate a client-side proxy class
at design/compile time with WSCF,
wsdl.exe or Visual Studio?
No need to know the exact Web Service description and endpoint at compile/design time. Just get your WSDL, specify the service (binding) to use and the operations to call, and voila! The library can be used especially good in testing scenarios.
The library is provided in source code.
