Microsoft's CCR vs Task Parallel Library

Question

Microsoft has at least two different approches to improved support for concurrent operations.

1) Is the Concurrency Coordination Runtime (CCR) which is part of Micro

Answer 1

It's not an either/or scenario. The CCR is a library that supports certain programming patterns. You can intermix CCR and TPL code like this, here is a Parallel.For inside of a Receive delegate:

using System;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.Ccr.Core;

namespace Demo
{
    public class Program
    {
        public static void Main(string[] args)
        {
            Dispatcher dispatcher = new Dispatcher();
            DispatcherQueue taskQueue = new DispatcherQueue("Demo", dispatcher);
            Port portInt = new Port();
            portInt.Post(Int32.Parse(args[0]));

            Arbiter.Activate(
                taskQueue,
                portInt.Receive(delegate(int count)
                {
                    Parallel.For(0, count, i =>
                    {
                        Console.Write(i.ToString() + " ");
                    });
                }
            ));
        }
    }
}
