Using AutoMapper

AutoMapper is a popular library that uses a convention-based, object-to-object mapper. Hence, AutoMapper lets you map objects without writing a ton of code, which you will see in a bit.

Now we need to set up our mapping of objects to objects automatically using the AutoMapper NuGet package, which is authored by the same person who wrote the MediatR library. I love AutoMapper because it simplifies mapping and projections.

The following command installs AutoMapper:

dotnet add package AutoMapper

The following command installs the AutoMapper extensions for ASP.NET Core:

dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection

Now let's create the files for the mapper. Create a new directory and name it Mappings inside Common of the Travel.Application project.

After creating the Mappings folder, create two C# files: ImapFrom.cs and MappingProfile.cs:

// IMapFrom.cs

using AutoMapper;
namespace Travel.Application.Common.Mappings...
