I looked at the code for the DynamicWebServiceHelpers sample on codeplex and it doesn't seem to deal with WSE3.0. So I guess the proxy that is generated by WebService.Load will not derive from WebServicesClientProtocol but from whatever is the base class for the old web services(I think it's SOAPHttpClientProtocol). I guess you could do one of two things. Compile your generated proxy(UserService.cs) into a dll and then use that from python Or port UserService.cs to python. You probably don't need the entire thing. My guess is that if u just set the url it might actually work - something like: userService = WebServicesClientProtocol() userService.Url = "http://www.example.com/Services/UserService.asmx"; TpPolicy.ApplyAutheticationTicket(userService, "admin", "admin")
