AutoMapper is well known in the .NET community. It bills itself as “a simple little library built to solve a deceptively complex problem - getting rid of code that maps one object to another,” and it does the job nicely.

In this tutorial, we are going to cover Asp.Net Core 3.0 Automapper implementation using a very simple example. Automapper is a very popular Object-to-Object mapping library that can be used to map objects. So, using automapper, we can map one object to another object throughout our application with just a little bit configuration.

We are going to start by looking into what the AutoMapper is and what problem it solves. Then, we are going to explain how we can use AutoMapper in our application. After that, we’ll learn about the usage guidelines and best practices. We’ll also take a look at what’s happening behind the scenes and how to flatten complex object models.
