In this chapter, we learned about Entity Framework and Entity Framework Core, and understood the features of each and the differences between the two. We also learned that we should use EF Core only if EF cannot be used or there is a pressing cross-platform requirement to use EF Core. We learned how to do CRUD operations using EF Core by creating a simple app. We then developed a simple movie booking app and learned how to deploy it using Visual Studio. We also saw how we can monitor our web app by enabling Application Insights. So far, we have only seen monolithic apps where all the APIs reside in one web app. If that one web app goes down, our entire app can come to a standstill. There is a way to circumvent this by deploying the app in smaller, independent modules, called microservices. In the next chapter, we will explore microservices.
