SYMPTOMS
Consider the following scenario. You install the MS07-040 update. You run a Microsoft ASP.NET 2.0 Web application that is built on the Microsoft .NET Framework 2.0. In this scenario, you may receive an exception error message that resembles the following:

Exception object: 026e3ce4

Exception type: System.Runtime.Serialization.Serialization

Exception Message: The constructor to deserialize an object of type ' ' was not found.

InnerException:

StackTrace (generated):

The stack trace that appears in the error message resembles the following:

   SP       IP       Function 00000000 00000001 System.Web.Hosting.ApplicationManager.RespondToPingIfNeeded 05BFF168 660D7ACD System.Web.Hosting.HostingEnvironment.RespondToPingButNotTooOften 05BFF1AC 660D796B System.Web.Hosting.HostingEnvironment.DecrementBusyCountInternal 05BFF1BC 6600F404 System.Web.HttpRuntime.FinishRequest(System.Web.HttpWorkerRequest, System.Web.HttpContext, System.Exception) 05BFF204 6600FADB System.Web.HttpRuntime.OnHandlerCompletion(System.IAsyncResult) 05BFF234 65FF4FED System.Web.HttpAsyncResult.Complete(Boolean, System.Object, System.Exception, System.Web.RequestNotificationStatus) 05BFF24C 65FD3404 System.Web.HttpApplication+ApplicationStepManager.ResumeSteps(System.Exception) 05BFF29C 65FF0BDA System.Web.HttpApplication.ResumeStepsFromThreadPoolThread(System.Exception) 05BFF2A8 65FF2204 System.Web.HttpApplication+AsyncEventExecutionStep.ResumeStepsWithAssert(System.Exception) 05BFF2BC 6632DC55 System.Web.HttpApplication+AsyncEventExecutionStep.OnAsyncEventCompletion(System.IAsyncResult) 05BFF2EC 65FF4FED System.Web.HttpAsyncResult.Complete(Boolean, System.Object, System.Exception, System.Web.RequestNotificationStatus) 05BFF304 6612A7EA System.Web.SessionState.SessionStateModule.PollLockedSessionCallback(System.Object)



CAUSE
After you install the MS07-040 update, a global counter is implemented in an application domain. The application domain is separate from the current application domain. After the HttpWorkerRequest.EndOfRequest method is called, the times of the global counter implementation decrease. During the cross-application domain call, the current Thread.CurrentPrincipal property should be serialized. If the application uses a custom UserPrincipal class that is not serializable, the application cannot serialize the current Thread.CurrentPrincipal property. Therefore, the application throws the exception.
