WCF services fail with NotSupportedException or ServiceActivationException after applying updates for .NET Framework 4

Symptoms
Consider the following scenario. You have a Windows Communication Foundation (WCF) service using Microsoft .NET Framework 4.0, hosted in a Microsoft Internet Information Services (IIS) web server. Under the SSL settings for the web application, you have enabled "Require SSL" as well as requiring client certificates. You then apply one of or more of the following hotfixes for WCF on .NET Framework 4:



In this configuration, when you try to browse to or make a method call to the WCF service that is using client certificate authentication, you may receive an error message and stack trace similar to the one below. You may receive this error even if you have not changed any other setting in the WCF configuration or IIS SSL configuration:
System.NotSupportedException: The SSL settings for the service 'None' does not match those of the IIS 'Ssl, SslNegotiateCert, SslRequireCert'. Stack Trace: [NotSupportedException: The SSL settings for the service 'None' does not match those of the IIS 'Ssl, SslNegotiateCert, SslRequireCert'.]   System.ServiceModel.Activation.HostedAspNetEnvironment.ValidateHttpsSettings(String virtualPath, Nullable`1& requireClientCertificate) +186762   System.ServiceModel.Channels.HttpsChannelListener.ApplyHostedContext(String virtualPath, Boolean isMetadataListener) +176   System.ServiceModel.Channels.HttpsTransportBindingElement.BuildChannelListener(BindingContext context) +123   System.ServiceModel.Channels.Binding.BuildChannelListener(Uri listenUriBaseAddress, String listenUriRelativeAddress, ListenUriMode listenUriMode, BindingParameterCollection parameters) +177   System.ServiceModel.Description.ServiceMetadataExtension.CreateGetDispatcher(Uri listenUri, Binding binding) +189   System.ServiceModel.Description.ServiceMetadataExtension.EnsureGetDispatcher(Uri listenUri, Boolean isServiceDebugBehavior) +229   System.ServiceModel.Description.ServiceMetadataBehavior.EnsureGetDispatcher(ServiceHostBase host, ServiceMetadataExtension mex, Uri url, String scheme) +195   System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost(ServiceDescription description, ServiceHostBase serviceHost) +3565   System.ServiceModel.ServiceHostBase.InitializeRuntime() +82   System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) +64   System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) +789   System.ServiceModel.HostingManager.ActivateService(String normalizedVirtualPath) +255   System.ServiceModel.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath) +1132 [ServiceActivationException: The service '/WCFService/Service1.svc' cannot be activated due to an exception during compilation.
