Question

I create a class library to put my repositories, domain model and my DTO.
When a user call ClienteRepository.GetById(1) for exemple, it should get the Client domain model and transform into a ClientDTO to return this, example:

public class ClientRepository{
     public ClientDTO GetById(int id){
          var clientDto = Mapper.Map<Client, ClientDTO>(_db.Client.Find(id));

          return clientDto;
     }

}

the problem is that Mapper.Map doesn’t work because I did not create the map (Mapper.CreateMap<Client, ClientDTO>()).

My question: How can I do this in a class library if I dont have global.asax to create it?

I solved my problem using https://github.com/davidebbo/WebActivator. Just create a new class and put this code:

[assembly: WebActivator.PostApplicationStartMethod(typeof (MapsInit), "Activate")]
namespace Database
{
    public static class MapsInit
    {
        public static void Activate()
        {
            Mapper.CreateMap<ClienteDto, Cliente>();
            Mapper.CreateMap<Cliente, ClienteDto>();
        }
    }
}
