  I´m usin VS 2019, .net core 3.1. I´m trying to create a crud using automapper. On the create action am getting an error, i´ve tried several forms but none seems to work

  Error:

  The entity type 'CustomerCountriesDto' was not found. Ensure that the entity type has been added to the model.

  On the view

  @model ManufacturaMVC.Models.CustomerCountries

  Controller

   private readonly ApplicationDbContext _context;
          private readonly IMapper _mapper;
  
          public CustomerCountriesController(ApplicationDbContext context, IMapper mapper)
          {
              _context = context;
              _mapper = mapper;
          }
  
  public async Task<IActionResult> Create([Bind("CustomerCountry")] CustomerCountries customerCountries)
          {
              if (ModelState.IsValid)
              {
                  //var model = _mapper.Map<CustomerCountriesDto>(customerCountries);
                  var user = _mapper.Map<CustomerCountries, CustomerCountriesDto>(customerCountries);
                  _context.Add(user);
                  await _context.SaveChangesAsync();                
                  return RedirectToAction(nameof(Index));
              }

  Error

  Missing type map configuration or unsupported mapping.
  

  Controller

  public async Task<IActionResult> Create([Bind("CustomerCountryDto")] CustomerCountriesDto customerCountries)
          {
              if (ModelState.IsValid)

                  var model = _mapper.Map<CustomerCountriesDto>(customerCountries);
                  var user = _mapper.Map<CustomerCountriesDto, CustomerCountries>(customerCountries);
                  _context.Add(user);
                  await _context.SaveChangesAsync();                
                  return RedirectToAction(nameof(Index));

   public class CustomerCountries
      {
          [StringLength(50, ErrorMessage = "Longitud máxima para el país: 50")]
          public string CustomerCountry { get; set; }
  
          public ICollection<CustomerRegions> CustomerRegions { get; set; }
      }
  
  public class ApplicationDbContext : DbContext
      {
          public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
              : base(options)
          {
  
          }
  
  
          public DbSet<Categories> Categories { get; set; }
          public DbSet<CustomerCities> CustomerCities { get; set; }
          public DbSet<CustomerCountries> CustomerCountries { get; set; }
  
  ...
   protected override void OnModelCreating(ModelBuilder modelBuilder)
          {
              modelBuilder.Entity<Categories>().HasKey(m => m.CategoryId);
              modelBuilder.Entity<CustomerCities>().HasKey(m => m.CustomerCity);
              modelBuilder.Entity<CustomerCountries>().HasKey(m => m.CustomerCountry);
  

  Can someone please tell me how is the correct way or, what is wrong?
