Using Redis as a cache on Azure

In this recipe, we will learn how to use Redis on Azure as a cache in-memory system with ASP.NET Core MVC applications.

Getting ready

First, we will connect to our Azure subscription, create a Redis cache provider, launch VS 2017, and create an empty web application.
