Automapper ninject dependencies

Question

I have a problem with Automapper on my site and I cannot find a solution. I created a class called AutoMapperProfile where I would like to place all my Maps

public class AutoMapperProfile: Profile
{
    private readonly IConfiguration _mapper;

    public AutoMapperProfile(IConfiguration mapper)
    {
        _mapper = mapper;
    }

    protected override void Configure()
    {
        base.Configure();

        _mapper.CreateMap<SlideDTO, Slide>();
        _mapper.CreateMap<Slide, SlideDTO>();
    }
}

For DI purposes, I use Ninject, so I added the following bindings to NinjectWebCommon:

kernel.Bind<IMappingEngine>().ToMethod(ctx => Mapper.Engine);
kernel.Bind<IConfigurationProvider>().ToMethod(x => Mapper.Engine.ConfigurationProvider);

The controller is as follows:

private readonly ISlideRepository slideRepository;
    private readonly IMappingEngine mappingEngine;

    public HomeController(
        ISlideRepository slideRepository,
        IMappingEngine mappingEngine)
    {
        this.slideRepository = slideRepository;
        this.mappingEngine = mappingEngine;
    }

    [HttpGet]
    public ActionResult Index()
    {
        var model = new IndexViewModel();
        var slide = slideRepository.GetSlide();
        model.Slide = mappingEngine.Map<SlideDTO, Slide>(slide);

        return View(model);
    }

When I switch from SlideDTO to Slide, I get the following error:

Missing type map configuration or unsupported mapping.

So I think I didn’t do the bindings correctly so that Automapper could see my maps, but I'm not sure how to fix it.

You do not need to type IConfigurationin AutoMapperProfile, it already inherits the method CreateMapfrom Profile.

, AutoMapperProfile :

public class AutoMapperProfile : Profile
{
    protected override void Configure()
    {
        this.CreateMap<SlideDTO, Slide>();
        this.CreateMap<Slide, SlideDTO>();
    }
}

, AutoMapper , :

Mapper.Engine.ConfigurationProvider.AddProfile<AutoMapperProfile>();

, AddProfile IConfigurationProvider ( ConfigurationProvider Engine).
