So far, we have been exploring the features and fundamentals of ASP.NET Core 2.0. The applications we have developed are good examples to learn the concepts but do not make use of data persistence. In this chapter, we will learn to do read, write, update, and delete data operations, making use of Entity Framework Core. We will also learn how to deploy a web app in Azure and monitor its health. We will demonstrate this by developing a simple movie booking web app, where a user can book a ticket for a movie. So, in this chapter, we will cover the following topics:

• Introducing Entity Framework and Entity Framework Core
• Getting started with Entity Framework Core
• Movie booking app requirements
• Designing the movie booking app
• Coding the movie booking app
• Deploying the movie booking app
• Monitoring the movie booking app

Let's start with an introduction to Entity Framework.
