.NET Standard 2.0 Cookbook

Creating a .NET Standard 2.0 library that uses delegates and lambda expressions

In this recipe, we will be using another functionality available in C#. These are called delegates and lambda expressions. What is a delegate in C#? As per the Microsoft documentation, it says:

"A delegate is a type that represents references to methods with a particular parameter list and return type."

Simply put, delegates are used to pass methods as arguments to other methods, and a lambda expression is an anonymous function that you can use to create delegates or expression tree types.
