Running tasks asynchronously

To understand how multiple tasks can be run simultaneously (at the same time), we will create a console application that needs to execute three methods.

There will be three methods that need to be executed: the first takes 3 seconds, the second takes 2 seconds, and the third takes 1 second. To simulate that work, we can use the Thread class to tell the current thread to go to sleep for a specified number of milliseconds.

Running multiple actions synchronously

Before we make the tasks run simultaneously, we will run them synchronously, that is, one after the other.

1. Create a new console application named WorkingWithTasks, add its folder to your Chapter13 workspace, and select the project as active for OmniSharp.
2. In Program.cs, import namespaces to work with threading and tasks, as shown in the following code:

   using System;
   using System.Threading;
   using System.Threading.Tasks; 
   using System.Diagnostics; 
   using static System...
