ChannelHandle:

private void HandleReceiveComplete(RequestContext context)
{
    if ((context == null) && this.incrementedActivityCountInConstructor)
    {
        this.listener.ChannelDispatcher.Channels.DecrementActivityCount();
    }

    {
        this.channel.HandleReceiveComplete(context);
    }
    else if ((context == null) && this.hasSession)
    {
        bool flag;
        lock (this.ThisLock)
        {
            flag = !this.doneReceiving;
            this.doneReceiving = true;
        }
        if (flag)
        {
            this.receiver.Close();
            if (this.idleManager != null)
            {
                this.idleManager.CancelTimer();
            }
            ServiceThrottle throttle = this.throttle;
            if (throttle != null)
            {
                throttle.DeactivateChannel();
            }
        }
    }
