Error message: "Two different contracts have the same ConfigurationName" when downloading wsdl from
- by rwwilden
I get the following error message when I try to use svcutil to generate a client proxy for a xamlx file that is hosted by AppFabric beta 2:
Two different contracts have the same ConfigurationName
I understand the message, however, I cannot find its cause or how to fix it. I'm following the 'Introduction to Workflow Services' lab from the VS2010RC training kit. The web application has two services: SubmitApplication.xamlx and EducationScreening.xamlx. I'm not sure why but both of them have four endpoints. If I take a look via the AppFabric Dashboard in IIS Mgmt Studio:
basicHttpBinding (Contract: *)
(Type: Application(Default))
netNamedPipeBinding (Contract: System.ServiceModel.Activities.IWorkflowInstanceManagement)
(Type: System (workflowControlEndpoint))
netNamedPipeBinding (Contract: *)
(Type: Application (Default))
serviceMetadataHttpGetBinding (Contract: serviceMetadataHttpGetContract)
(Type: System (serviceMetadataEndpoint))
When taking a look at the SubmitApplication.xamlx in a browser, I see the following stacktrace:
[InvalidOperationException: Two different contracts have the same ConfigurationName.]
System.ServiceModel.Activities.WorkflowServiceHost.CreateDescription(IDictionary`2& implementedContracts) +361

System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +179150
System.Web.AsyncEventExecutionStep.OnAsyncEventCompletion(IAsyncResult ar) +107
Can anyone tell me what I'm doing wrong?
I haven't configured any of the bindings myself. The BasicHttpBinding is what you get by default in .NET 4 when hosting a service inside a web application. The other bindings are configured by AppFabric. I can't find their configuration anywhere.
Kind regards,
