AutoMapper is the best solution.

You can do it very easily like this :

    Mapper.CreateMap();
    Mapper.CreateMap();

    Mapper.CreateMap();
    Mapper.CreateMap();

Note : Because AutoMapper will automatically map the List to List.since they have same name, and there is already a mapping from Person to PersonDto.

If you need to know how to inject it to ASP.net core,you have to see this article : Integrating AutoMapper with ASP.NET Core DI
