C# SeviceSecurityContext.Current is not preseved QueueUserWorkItem

When delegating a thread using ThreadPool.QueueuserWorkItem the ServiceSecurityContext.Current does not persist (returns null). Several of the methods I am calling require that the security context be valid prior to returning information.

Is there a way to create a 开发者_Go百科thread that will run with the same security context? Is it possible to allow the current security context to persist or does a thread specific security context need to be setup?
