Can WaitHandle.WaitOne with ExitContext flag be used without ContextBoundObject class?

MSDN documentation suggests that there may be other ways of using ExitContext flag. See WaitHandle.WaitOne() What other ways are there to enter a non-default context outside of using a C开发者_如何学运维ontextBoundObject inherited class? (I can't use ContextBoundObject in my application)

The clue is in this sentence.

Even if you are currently executing a method on a class that does not derive from ContextBoundObject, like String, you can be in a nondefault context if a ContextBoundObject is on your stack in the current application domain.

So basically you could call WaitOne from within a class that does not subclass ContextBoundObject nor would you have any preconceived notion that a ContextBoundObject was in any way involved with your code and yet the thread in question could be in a nondefault context because somewhere way up in the call stack an instance method of a ContextBoundObject class could be running unbeknown to you.

Outside of that lone exception there are no other ways of entering into a nondefault synchronization context.

There is a pretty good article on threading with additional information related to synchronization contexts which can be found here.
