Using the await operator in a lambda expression

This recipe will show you how to use await inside a lambda expression. We will write an anonymous method that uses await and get a result of the method execution asynchronously.

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\Recipe2.

How to do it...

To write an anonymous method that uses await and get a result of the method execution asynchronously using the await operator in a lambda expression, 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 async Task AsynchronousProcessing()
   {
     Func<string, Task<string>> asyncLambda = async...
