Unable to Add Additional Fields in Aspnetuser table

Question

I have created a custom fields and trying to insert the custom fields in aspnetusers tables, but the additional fiels data is not inserted. Below is the code i tried:

            var identityUser = new CreateUser
            {

                Email = model.Email,
                UserName = model.Email,
                TenantId = obj.ToString(),
                IsAdmin= true


            };
            var result = await _userManager.CreateAsync(identityUser, model.Password);
            var assignRole = await _userManager.AddToRoleAsync(identityUser, "ADMIN");

Class:

    public class CreateUser:IdentityUser
{
    public string FirstName { get; set; }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
    public string OrganizationName { get; set; }
    public string Address { get; set; }
    public string Address2 { get; set; }

    public string TenantId { get; set; }
    public bool IsAdmin { get; set; }
}

DbContext:

  public class ApplicationDBContext:IdentityDbContext<IdentityUser>
{

    public ApplicationDBContext(DbContextOptions options) : base(options)
    {


    }

}

StartUp

            //Configure Entity Frameworkcore with SQL Server
        services.AddDbContext<ApplicationDBContext>(options =>
        {
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
        });

Is anything missing here, only the original fields gets updated while the added fields value is not inserted.

Answer 1

Here should be the CreateUser:

public class ApplicationDBContext : IdentityDbContext<CreateUser>
{

    public ApplicationDBContext(DbContextOptions options) : base(options)
    {

    }

}

Startup.cs:

services.AddIdentity<CreateUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders()
    .AddDefaultUI();

Dependency injection:

public class HomeController : Controller
{
    private readonly UserManager<CreateUser> _userManager;

    public HomeController(UserManager<CreateUser> userManager)
    {
        _userManager = userManager;
    }

    //...

}

The detail steps to customize could be found in Customize the model document .
