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. So, first-of-all, we will create a new Asp.Net Core project in Visual Studio 2019 and then we will install AutoMapper and then we will configure AutoMapper in our project and then we will add model class and a Dto (Data Object Mapper) class and then we will map both (Model class and Dto) and then finally we will see the output.
