In my Application layer, I have the following classes:

public class AutoMapperConfig
    {

        public static MapperConfiguration RegisterMappings()
        {
            return new MapperConfiguration(cfg =>
            {
                cfg.AddProfile(new DomainToViewModelMappingProfile());
                cfg.AddProfile(new ViewModelToDomainMappingProfile());
            });
        }
    }

public class DomainToViewModelMappingProfile : Profile
    {
        public DomainToViewModelMappingProfile()
        {
            CreateMap<Customer, CustomerViewModel>();
        }
    }

public class ViewModelToDomainMappingProfile : Profile
    {
        public ViewModelToDomainMappingProfile()
        {
            CreateMap<CustomerViewModel, RegisterNewCustomerCommand>()
                .ConstructUsing(c => new RegisterNewCustomerCommand(c.Name, c.Email, c.BirthDate));
            CreateMap<CustomerViewModel, UpdateCustomerCommand>()
                .ConstructUsing(c => new UpdateCustomerCommand(c.Id, c.Name, c.Email, c.BirthDate));
        }
    }

In my Asp.Net MVC layer, I have the Startup.cs class which through the services.AddAutoMapper () method; initializes my Automapper configuration classes, except that it calls the method and does not pass through the classes mentioned above. Consequently, when I have to save some registry in my bank, an error occurs in my controller related to Automapper:

Error: "+ $ exception {AutoMapper.AutoMapperConfigurationException: Unmapped members were found. Review the types and members below. Add a custom mapping expression, ignore, add a custom resolver, or modify the source / destination type

For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters

            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            app.UseStaticFiles();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }

        private static void RegisterServices(IServiceCollection services)
        {
            // Adding dependencies from another layers (isolated from Presentation)
            NativeInjectorBootStrapper.RegisterServices(services);
        }
    }

How do I resolve this?

Since the version of the course of Eduardo Pires there have been changes in the Automapper, which make the configuration easier and readable. I'll demonstrate.

First create the mapping profile class, just like you did, but only one, since we will use the .ReverseMap() method, which already does the reverse mapping of objects automatically.

public class MapProfile:AutoMapper.Profile
    {
        public MapProfile()
        {
            // Core
            CreateMap<SchoolPrincipal, SchoolPrincipalViewModel>().ReverseMap();
        }
    }

Next, create the class that will start Automapper in class Startup

public class MapConfiguration
{
    public static void RegisterMapProfile()
    {
        Mapper.Initialize(c =>
        {
            c.AddProfile<MapProfile>();
        });
    }
}

Now in method ConfigureServices(IServiceCollection services) of class Startup include the line:

MapConfiguration.RegisterMapProfile();

This code is leading me to an infinite cycle and I can not understand why Date choices

Hello @

I found the solution to the problem.

In the Startup.cs class, just swap:

services.AddAutoMapper ()

by:

services.AddAutoMapper ( Assembly.GetAssembly (typeof (AutoMapperConfig)) )

Here it worked for me. I hope I have helped!
