Calling helper class that refrence to WCF web service

Question

Hi I have a BizTalk projects that calls a helper class. now the helper class receive the message and a counter and is suppose via the class to create a login to a WCF
web service and then synchronize the message to this WCF web service.<o:p></o:p>
this is class:<o:p></o:p>
public static string SyncConcerto(XLANGMessage msg, int count)
SelectResponse select = (SelectResponse)msg[0].RetrieveAs(typeof(SelectResponse));
ConcertoService.ExternalMappingServiceClient concertoServ = new ConcertoService.ExternalMappingServiceClient();
ConcertoService.ExternalMappingItem extMapItem = new ConcertoService.ExternalMappingItem();
ConcertoService.ExternalMappingServiceResponse extLogonResp = new ConcertoService.ExternalMappingServiceResponse();
ConcertoService.ExternalMappingServiceResponse extSyncResp = new ConcertoService.ExternalMappingServiceResponse();
extLogonResp = concertoServ.Logon("*****", "******", true);
if (extLogonResp.StatusCode == 1)
if (count>0)
for (int i = 0; i < count; i++)
extMapItem.Attribute1 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.REGION_NAME;
extMapItem.Attribute2 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PROJECT_NUMBER;
extMapItem.Attribute3 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PRODUCT_NAME;
extMapItem.ProjectName = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PROJECT_NAME;
extMapItem.ProjectMgr = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PM_NAME;
//extMapItem.ProjectMgr = select.SelectResult.CNS_CONCERTO_PROJECTSRECORDSELECT.PM_NAME;
extMapItem.Division = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.DIVISION_NAME;
extMapItem.Subject = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.CUSTOMER_NAME;
extMapItemArr[i] = extMapItem;
extSyncResp = concertoServ.SynchronizeExternalAttributeData(extMapItemArr);
if (extSyncResp.StatusCode == 1)
return "sync success login success";
else
return "success login sync faild";
else if (extLogonResp.StatusCode == 2)
return "TimeOut";
return "Failed";
Now it keeps throwing exception in this line of code: ConcertoService.ExternalMappingServiceClient concertoServ = new ConcertoService.ExternalMappingServiceClient();
saying he needs a valid endpoint. but he has the app.config file already that stats his endpoint.
What am I doing wrong, since I have never done a thing like that before.
And also I can't use the WCF web service in the normal BIZTALK way due to login operation he needs to do. <o:p></o:p>
Any advice on how to continue?<o:p></o:p>

Answer 1

the WCF has a logon operation where I enter a user name and password, it doesn't return a session key meaning I can't send a message to the WCF WS (Biztalk is stateless) that doe's the logon operation and the synchronize operation. so I had to do it with
the helper class. 
and Morten I know this is very bad practice but I don't have choice for now. 
Morten another question since we are using Biztalk 2013 (New Enviroment) our BTSNTSvc.exe.config is empty:
<?xml version="1.0" ?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" />
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="BizTalk Assemblies;Developer Tools;Tracking;Tracking\interop" />
</assemblyBinding>
</runtime>
<system.runtime.remoting>
<channelSinkProviders>
<serverProviders>
<provider id="sspi" type="Microsoft.BizTalk.XLANGs.BTXEngine.SecurityServerChannelSinkProvider,Microsoft.XLANGs.BizTalk.Engine" securityPackage="ntlm" authenticationLevel="packetPrivacy" />
</serverProviders>
</channelSinkProviders>
<application>
<channels>
<channel ref="tcp" port="0" name="">
<serverProviders>
<provider ref="sspi" />
<formatter ref="binary" typeFilterLevel="Full"/>
</serverProviders>
</channel>
</channels>
</application>
</system.runtime.remoting>
</configuration>
where do I insert my end point and how?
