If you have an external web service reference in your sharepoint solution, you can use web.config configuration like: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <bindings> <wsHttpBinding> <binding name="WSHttpBinding\_ISuperService" > <security mode="None"> <message clientCredentialType="None" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://super.domain/SuperService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding\_ISuperService" contract="ISuperService" name="SuperServiceEndpoint"> </endpoint> </client> </system.serviceModel> ```security mode is set to "None". Then in code just get this configuration: var proxy = new SuperServiceClient(“SuperServiceEndpoint”); var result = proxy.GetSomething(); var binding = new WSHttpBinding(); binding.
