Producer Consumer Pattern with HandOff point

// Both Data Queue and Queue under SynchronizationContext allow handoff of data
// Data Consumer can be parallel Enumerable or Subscribe to Observables
// UI can only singled threaded Async or sync

        void BlockingCollectionAsQueue()
        {
            BlockingCollection<string> ServerData = new BlockingCollection<string>(10000);
            ServerData.Add("Data");
            ServerData.CompleteAdding();
            string data1;
            ServerData.TryTake(out data1, TimeSpan.FromMilliseconds(2));
            IEnumerable<string> data = ServerData.GetConsumingEnumerable();
            foreach (var v in data.AsParallel().AsOrdered().Select(l => Regex.Replace(l, @"\s+", ""))) ;
        }

        void UIMarshalling()
        {
            ThreadPool.QueueUserWorkItem((s) =>
            {
                //do some server side work
                // UIControl.Invoke();
                //Dispatcher.Invoke();
                SendOrPostCallback spcb = new SendOrPostCallback((obj) => { });
                // SynchronizationContext =WPF.Dispatcher or WF.Control.Invoke
                SynchronizationContext.Current.Send((state) =>
                {
                    //UI.Property="";
