Summary

A hotfix rollup is available for Windows Communication Foundation (WCF) for the Microsoft .NET Framework 3.0 Service Pack 2 and for the Microsoft .NET Framework 3.5 Service Pack 1.

Fixes included in this hotfix rollup

This hotfix rollup includes fixes for the following issues.

Issue 1

You run a peer channel application that uses WCF in the .NET Framework 3.0 and joins a mesh for communication. The application crashes because of a Time Out exception that resembles the following:

Exception type: System.ApplicationException
Message: This operation returned because the timeout period expired. (Exception from HRESULT: 0x800705B4)
InnerException: <none>
StackTrace (generated):

000000001BDBED70 000007FEF92E95AA System.Security.SecurityContext.Run(System.Security.SecurityContext, System.Threading.ContextCallback, System.Object)
000000001BDBEDB0 000007FEF6C77090 System.ServiceModel.Channels.IOThreadScheduler+CriticalHelper+WorkItem.Invoke()
000000001BDBEE00 000007FEF6C76FB1 System.ServiceModel.Channels.IOThreadScheduler+CriticalHelper.ProcessCallbacks()
000000001BDBEE70 000007FEF6C76E33 System.ServiceModel.Channels.IOThreadScheduler+CriticalHelper.CompletionCallback(System.Object)This issue occurs because of a deadlock that occurs when the PeerChannel client application does not correctly update its registrations or when a node in the mesh disconnects ungracefully. When this occurs, theĀ CustomPeerResolverService object times out when it tries to obtain the internal ReaderWriterLock object.

Issue 2

You run a WCF service that meets the following conditions:

  • The service uses only one proxy and calls many operations in the proxy.

  • The service uses a duplex messaging pattern.

  • An asynchronous result is added to the RequestReplyCorrelator object and cannot be removed until a response is provided.


When an error occurs in a request operation, the request cannot be processed. Additionally, the memory for the related request message and customer object cannot be released.

This issue occurs because of a memory leak in the ChannelFactoryRef object.
