Symptoms
Consider the following scenario:
-
You use a Microsoft .NET Framework 3.0-based client application that uses the HTTP protocol over Secure Sockets Layer (SSL) to access a Windows Communication Foundation (WCF) service.
-
A System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest object is invoked on the client application.
-
You close the connection to the WCF service. Or, the WCF service becomes unavailable. A WebException exception is encountered.
In this scenario, the memory of the HttpChannelRequest object is not released. Therefore, a memory leak occurs, and the performance of the client application might decrease.
