Learning code-first development and migrations

In this section, we are going to explore EF Core code-first development by building a simple ASP.NET Core Web API application to perform basic database operations.

Before we get our hands dirty with coding, let's first review what ASP.NET Core Web API is.

Reviewing ASP.NET Core Web API

There are many ways to enable various systems to access data from one application to another. A few examples of communications are HTTP-based APIs, web services, WCF servers, event-based communication, message queues, and many others. Nowadays, HTTP-based APIs are the most commonly used means of communication between applications.
