How do I use DTOs in ASP.NET Core?

DTOs, or Data Transfer Objects, are used to transfer data between layers in an application. In ASP.NET Core, you can create DTO classes to define the structure of the data you want to send or receive.

Can you give me an example of a DTO in ASP.NET Core?

Sure! For instance, you might have a UserDto class with properties like Id, Name, and Email. This class can be used to transfer user data between your API and the client.

How do I map between DTOs and my entity models?

You can use libraries like AutoMapper to simplify the mapping process. Just configure the mappings in your startup and use it to convert between your DTOs and entity models.

What are the benefits of using DTOs?

DTOs help in reducing the amount of data sent over the network, improve security by exposing only necessary data, and decouple your API from your database models.
