 using System.Threading;

 namespace SynchronizationTest003
 {
     class Program
     {
         static void Main(string[] args)
         {
             SynchronizationContext sc = new SynchronizationContext();
             Console.WriteLine(Thread.CurrentThread.ManagedThreadId);
             testA(sc);

             Console.ReadKey();
         }

         public static void testA(object state)
         {
             SynchronizationContext sc = state as SynchronizationContext;
             Console.WriteLine("Start");
             Console.WriteLine("Func A's ManagedThreadID is: " + Thread.CurrentThread.ManagedThreadId);
             sc.Post(testB,state);
             Console.WriteLine("End");
         }

         public static void testB(object state)
         {
             Console.WriteLine("Func B's ManagedThreadID is: " + Thread.CurrentThread.ManagedThreadId);
             Thread.Sleep();
             SynchronizationContext sc = state as SynchronizationContext;
             sc.Post(testC,null);
         }

         public static void testC(object state)
         {
