iis-7.5 - KB2742595 之后 System.ServiceModel.Dispatcher.ClientRuntime 中的 InvalidProgramException

Question

当我在我的网络服务器上安装安全补丁 KB2742595 时，我开始收到“异常类型：InvalidProgramException

    Exception message: Common Language Runtime detected an invalid program.
   at System.ServiceModel.Dispatcher.ClientRuntime..ctor(String contractName, String contractNamespace)"

Stack trace:    at System.ServiceModel.Dispatcher.ClientRuntime..ctor(String contractName, String contractNamespace)
   at System.ServiceModel.Description.DispatcherBuilder.BuildProxyBehavior(ServiceEndpoint serviceEndpoint, BindingParameterCollection& parameters)
   at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint, Boolean useActiveAutoClose)
   at System.ServiceModel.ChannelFactory.CreateFactory()
   at System.ServiceModel.ChannelFactory.OnOpening()
   at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout)
   at System.ServiceModel.Channels.CommunicationObject.Open()

配置是 W Server 2K8 SP1，并通过 nettcp 与 WCF 服务通信。请帮忙。
