移动WCF服务Azure的VM

Question

我有一个运行良好，而在本地IIS托管，而是给出了一个蓝色的VM IIS托管时，下列异常的WCF服务的服务：

DispatchOperation requires Invoker. 
Exception Details: System.InvalidOperationException: DispatchOperation requires Invoker 

堆栈跟踪：

[InvalidOperationException: DispatchOperation requires Invoker.] 
    System.ServiceModel.Dispatcher.DispatchOperationRuntime..ctor(DispatchOperation operation, ImmutableDispatchRuntime parent) +17276262 
    System.ServiceModel.Dispatcher.ImmutableDispatchRuntime..ctor(DispatchRuntime dispatch) +824 
    System.ServiceModel.Dispatcher.DispatchRuntime.GetRuntimeCore() +114 
    System.ServiceModel.Dispatcher.ChannelDispatcher.OnOpened() +520 
    System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) +766 
    System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) +260 
    System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) +742 
    System.ServiceModel.HostingManager.ActivateService(ServiceActivationInfo serviceActivationInfo, EventTraceActivity eventTraceActivity) +126 
    System.ServiceModel.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath, EventTraceActivity eventTraceActivity) +901 

[ServiceActivationException: The service '/PidPlusService.svc' cannot be activated due to an exception during compilation. The exception message is: DispatchOperation requires Invoker..] 
    System.Runtime.AsyncResult.End(IAsyncResult result) +650220 
    System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result) +210733 
    System.Web.CallHandlerExecutionStep.OnAsyncHandlerCompletion(IAsyncResult ar) +282 

我有服务中的svc文件，web.config文件和dll。服务项目是一个类库项目，是生成dll的解决方案的一部分。 在Azure中托管代码时是否需要更改某些内容？或者它是一个配置问题？

您必须将虚拟机配置为支持WCF，就像您使用本地内部部署IIS计算机一样。确保在Azure中的虚拟机上配置了these settings。

此外，您可能需要在Windows功能的WCF Http激活中启用（.NET Framework 3.5）。如果您的目标是.NET Framework 4.5，请确保已启用“WCF服务”（.NET Framework 4.5高级服务）。
