KB2742595之后的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，我开始得到“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传递WCF服务。 请帮忙。
