Unable to resolve service for type ‘Microsoft.AspNetCore.Identity.UserManager` while attempting to activate ‘AuthController’

by

You need to use the same user data model in SignInManager, UserManager and services.AddIdentity. Same principal is true if you are using your own custom application role model class.

So, change 

services.AddIdentity<IdentityUser, IdentityRole>(options =>
    {
        options.User.RequireUniqueEmail = false;
    })
    .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
    .AddDefaultTokenProviders();

to

services.AddIdentity<Automobile.Models.Account, IdentityRole>(options =>
    {
        options.User.RequireUniqueEmail = false;
    })
    .AddEntityFrameworkStores<Providers.Database.EFProvider.DataContext>()
    .AddDefaultTokenProviders();
