Running tasks in parallel

This recipe shows how to handle many asynchronous tasks that are running simultaneously. You will learn how to be notified effectively when all tasks are complete or any of the running tasks have to finish their work.

Getting ready

To start this recipe, you will need Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter4\Recipe8.

How to do it...

To run tasks in parallel, 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.Collections.Generic;
   using System.Threading.Tasks;
   using static System.Console;
   using static System.Threading.Thread;

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

   static int TaskMethod(string name, int seconds)
   {
     WriteLine(
       $"Task {name} is running on a thread id " +
       $"{CurrentThread.ManagedThreadId}. Is thread pool thread: " +
       $"...
