Project – Mapping service

The goal is to simplify the implementation of the mapper façade with a universal interface.

We are going to use our third diagram to achieve that goal. Here's a reminder:

Figure 13.4 – Object mapping using a single IMapper interface

Instead of naming the interface IMapper, I found IMappingService to be more suitable because it is not mapping anything; it is a dispatcher, sending the mapping request to the right mapper. Let's take a look:

namespace Core.Interfaces
{
    public interface IMappingService
    {
        TDestination Map<TSource, TDestination>(TSource entity);
    }
}

That interface is self-explanatory; it maps any TSource to any TDestination.

On the implementation side, we are leveraging the Service Locator pattern, so I called the implementation ServiceLocatorMappingService:

namespace Web.Services
{
    public class ServiceLocatorMappingService : IMappingService
    ...
