Impossible de résoudre le service pour le type IEmailSender lors de la tentative d'activation de RegisterModel

J'utilise Identity et j'ai un problème que je crée un nouveau projet d'exemple et avec l'authentification individuelle et l'identité d'échafaudage InvalidOperationException: Impossible de résoudre le service pour le type 'Microsoft.AspNetCore.Identity.UI.Services.IEmailSender' tout en essayant d'activer ' MASQ.Areas.Identity.Pages.Account.RegisterModel '.

Il y a deux façons de procéder:

  1. supprimez la services.AddDefaultTokenProviders() dans la ConfigurureServices() pour désactiver two-factor authentication (2FA):

// fichier: Startup.cs:

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<ApplicationDbContext>();
    ///.AddDefaultTokenProviders(); /// remove this line
  1. Ajoutez vos propres implémentations IEmailSender et ISmsSender à DI contianer si vous souhaitez activer 2FA

// fichier: Startup.cs

services.AddTransient<IEmailSender,YourEmailSender>();
services.AddTransient<IEmailSender,YourSmsSender>();

Les deux devraient fonctionner.
