In my search of doing my job faster in the development of web services i found this pretty helpful tool: WSCF - Web Services Contract First. This helps us generating .net code (C#, vb.net) from WSDL, XSD and so on. You can generate proxy classes for .net/java or any other client and also .net web service - server side code all from Visual Studio 2005.
