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. Use your preferred code editor to add a new console app to the Chapter12 solution/workspace named WorkingWithTasks.
2. In Visual Studio Code, select WorkingWithTasks as the active OmniSharp project.
3. In Program.cs, import the namespace to work with a stopwatch (namespaces for working with threading and tasks are implicitly imported), and statically import Console...
