to fix wcf soap client error :

WSDLService :Processing service xxx found no port definitions HRESULT=0x80070057: The parameter is incorrect.
update web.config:
...

<services>
            <service name="Business.WebService.Service1" behaviorConfiguration="Business.WebService.Service1Behavior">
                <!-- Service Endpoints -->
find this line: <endpoint address="" binding="wsHttpBinding" contract="Business.WebService.IService1"> 
and replace with this one : <endpoint address="" binding="basicHttpBinding" contract="Business.WebService.IService1">

basicHttpBinding is compatible with old soap clients.
