Shared code across Azure Functions using class libraries

So far, you have learned how to reuse a Helper method within an Azure function app. However, you cannot reuse it across other function apps or any other type of application, such as a web app or a WPF application. In this recipe, we will develop and create a new .dll file, and you will learn how to use the classes and their methods in Azure Functions.

How to do it...

Perform the following steps:

  1. Create a new Class Library application using Visual Studio. I used Visual Studio 2017:
  1. Create a new class named Helper and paste the following code into the new class file:
namespace Utilities
public class Helper
public static string GetReusableFunctionOutput...
