Using the await operator with consequent asynchronous tasks

This recipe will show you how exactly the program flows when we have several consecutive await methods in the code. You will learn how to read the code with the await method and understand why the await call is an asynchronous operation.

Getting ready

To step through this recipe, you will need Visual Studio 2015. There are no other prerequisites. The source code for this recipe can be found at BookSamples\Chapter5\Recipe3.

How to do it...

To understand a program flow in the presence of consecutive await methods, 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.Tasks;
   using static System.Console;
   using static System.Threading.Thread;

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

   static Task AsynchronyWithTPL()
   {
     var containerTask = new Task(() => { 
       Task<string> t = GetInfoAsync...
