Posting an asynchronous operation on a thread pool

This recipe will describe how to put an asynchronous operation on a thread pool.

Getting ready

To step into this recipe, you will need Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter3\Recipe2.

How to do it...

To understand how to post an asynchronous operation on a thread pool, perform the following steps:

1. Start Visual Studio 2015. Create a new C# console application project.
2. In the Program.cs file, add the following using directives:

   using System;
   using System.Threading;
   using static System.Console;
   using static System.Threading.Thread;

3. Add the following code snippet below the Main method:

   private static void AsyncOperation(object state)
   {
     WriteLine($"Operation state: {state ?? "(null)"}");
     WriteLine($"Worker thread id: {CurrentThread.ManagedThreadId}");
     Sleep(TimeSpan.FromSeconds(2));
   }

4. Add the following code snippet inside the Main method...
