What is AutoMapper? #
AutoMapper is a library that helps us to transform one object type to another in a very easy accurate way. We start by creating our web API. dotnet new webapi -n SampleMapper. Once we create our application we need to install the AutoMapper nuget package into our application.

What is DTO used for #
A DTO is helpful whenever you need to group values in ad hoc structures for passing data around. From a pure design perspective, DTOs are a solution really close to perfection. DTOs help to further decouple presentation from the service layer and the domain model.
