c# - wcf client .exception "The provided URI scheme 'http' is invalid; expected 'https" -

i creating client wcf service. service works across sharepoint(i don't know, maybe it's important)

config:

    <system.servicemodel>            <bindings>         <basichttpbinding>           <binding name="commonservicejssoap_binding" >             <security mode="transport">               <transport clientcredentialtype="windows"/>             </security>           </binding>         </basichttpbinding>     </bindings>     <client>         <endpoint address="http://blackwhite/_layouts/15/eos/commonservicejs.asmx"             binding="basichttpbinding" bindingconfiguration="commonservicejssoap_binding"             contract="commonservices.commonservicejssoap" name="commonservicejssoap_endpint" />     </client> </system.servicemodel> 

code:

 commonservicejssoapclient client = new commonservicejssoapclient();         client.open(); 

open() throw argumentexception{"the provided uri scheme 'http' invalid; expected 'https'.\r\nparameter name: via"}

commonservicejssoapclient autogenerated visual studio(vs add service reference)

in binding security mode use transportcredentialonly instead of transport
