从AppFabric Beta 2中的xamlx下载wsdl时出现错误消息:“两个不同的契约具有相同的配置名称”

当我试图使用 svcutil 为 xamlx AppFabric Beta 2托管的文件:

两个不同的合同具有相同的配置名称

我理解这个信息,但是,我找不到它的原因或如何解决它。我正在关注VS2010RC培训工具包中的“工作流服务简介”实验室。web应用程序有两个服务:submitapplication.xamlx和educationscreening.xamlx。我不知道为什么,但他们都有四个终点。如果我通过IIS管理工作室中的AppFabric仪表板查看:

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))

在浏览器中查看submitapplication.xamlx时,我看到以下stacktrace:

[InvalidOperationException: Two different contracts have the same ConfigurationName.]
System.ServiceModel.Activities.WorkflowServiceHost.CreateDescription(IDictionary`2& implementedContracts) +361
System.ServiceModel.ServiceHostBase.InitializeDescription(UriSchemeKeyedCollection baseAddresses) +174

[ServiceActivationException: The service '/HRApplicationServices/SubmitApplication.xamlx' cannot be activated due to an exception during compilation. The exception message is: Two different contracts have the same ConfigurationName..]

System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +179150
System.Web.AsyncEventExecutionStep.OnAsyncEventCompletion(IAsyncResult ar) +107

有人能告诉我我做错了什么吗?

我自己还没有配置任何绑定。BasicHttpBinding是在.NET4中在Web应用程序中托管服务时默认获得的。其他绑定由appfabric配置。我在任何地方都找不到它们的配置。

更新 :删除了一个xamlx服务( EducationScreening.xamlx )没有效果。
