c# - How to call a service using multiple Endpoint URIs -

to put context, have client application attempt call webservice deployed on multiple web servers. uri list obtained settings.settings file of client , foreach loop cycle through uris until available service responds.

let's have service following contract:

[servicecontract]     public interface icmmsmanagerservice     {         [operationcontract]         serverinfo getserverinfo(string systemnumber);     } 

in web.config of service's project, have defined cmmsmanager service the endpoint name: basichttpbinding_iworkloadmngrservice

 <system.servicemodel>     <services>       <service name="workloadmngr">         <endpoint  binding="basichttpbinding" contract="imetadataexchange" />       </service>       <service name="cmmsmanager">         <endpoint  binding="basichttpbinding" contract="imetadataexchange" name="basichttpbinding_iworkloadmngrservice" />       </service>     </services>      <client>       <remove contract="imetadataexchange" name="sb" />     </client>      <behaviors>       <servicebehaviors>         <behavior>           <servicemetadata httpgetenabled="true" />           <servicedebug includeexceptiondetailinfaults="true" />         </behavior>       </servicebehaviors>     </behaviors>     <bindings>       <basichttpbinding>         <binding>           <security mode="transportcredentialonly">             <transport clientcredentialtype="windows"/>           </security>         </binding>       </basichttpbinding>     </bindings>     <servicehostingenvironment multiplesitebindingsenabled="true" />    </system.servicemodel> 

on client side, have following code executed when application starts:

private void querywebserviceurls() {     var webserviceurls = properties.settings.default.webserviceurls;      foreach (var webserviceurl in webserviceurls)     {         try         {                var client = new cmmsmanagerserviceclient("basichttpbinding_iworkloadmanagerservice");             client.endpoint.address = new endpointaddress(new uri(webserviceurl),                 client.endpoint.address.identity, client.endpoint.address.headers);             client.open();             var result = client.getserverinfo("test");         }         catch (endpointnotfoundexception e)         {             continue;         }         catch (invalidoperationexception e)         {             break;         }     } } 

but application crashes invalidoperationexception when cmmsmanagerserviceclient class instanciated.

could not find endpoint element name 'basichttpbinding_iworkloadmngrservice' , contract 'comclientservice.icmmsmanagerservice' in servicemodel client configuration section. might because no configuration file found application, or because no endpoint element matching name found in client element.

i have following configuration in app.config:

<system.servicemodel>     <bindings>       <basichttpbinding>         <binding name="basichttpbinding_icmmsmanagerservice">           <security mode="transportcredentialonly">             <transport clientcredentialtype="windows" />           </security>         </binding>       </basichttpbinding>     </bindings>     <client>       <endpoint address="http://localhost/workloadmngr/cmmsmanagerservice.svc"           binding="basichttpbinding" bindingconfiguration="basichttpbinding_icmmsmanagerservice"           contract="comclientservice.icmmsmanagerservice" name="basichttpbinding_icmmsmanagerservice" />     </client>   </system.servicemodel> 

i thought valid passing basichttpbinding_icmmsmanagerservice parameter cmmsmanagerserviceclient class. have no clue missing @ moment... ideas?

the error telling what's wrong: there no endpoint name basichttpbinding_iworkloadmngrservice. app.config says endpoint called basichttpbinding_icmmsmanagerservice code should be:

var client = new cmmsmanagerserviceclient("basichttpbinding_icmmsmanagerservice"); 

hope helps.
