How to access ContextBoundObject object in IMessageSync.SyncProcessMessage method

Question

Hi,

is there a way to access object on which intercepted method was called inside custom IMessageSink? I would like to set some properties on that object that would scope only for duration of method call, manage them, dispose etc...

public IMessage SyncProcessMessage(IMessage msg) {
    Preprocess(msg);
    IMessage returnMethod = m_next.SyncProcessMessage(msg);
    PostProcess(msg, returnMethod);
    return returnMethod;
}

I know it possible to pass data between ContextBoundObject and IMessageSink using LogicalCallContext.SetData, but i would prefet to work directly on ContextBoundObject instance.

Thanks,Pawel
