Creating Login System

Question

I am trying to create my own login system but for some reason it wont add a new user to my MSSMS database

i have already created the migration and the tables are in the database 

 

Startup Code:  

public void ConfigureServices(IServiceCollection services)
        {
            services.AddIdentity<AppUser, AppRole>(options =>
             {
                 options.User.RequireUniqueEmail = true;


             }).AddEntityFrameworkStores<IdentityAppContext>()
             .AddDefaultTokenProviders();

            services.ConfigureApplicationCookie(config =>
           {
               config.Cookie.Name = "Login_Cookie1";
               config.LoginPath = "/Account/login";
           });

            services.AddDbContext<IdentityAppContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("Master")));

            services.AddControllersWithViews();
        }

 

 appsettings.json:

"ConnectionStrings": {
    "Master": "Server=LAPTOP-VI29TVE0;Database=MasterDb;Trusted_Connection=True;MultipleActiveResultSets=true"
  }

 

Controller:

public class AccountController : Controller
    {
        private UserManager<AppUser> Usermgr { get; }
        private SignInManager<AppUser> SignInmgr { get; }
        public AccountController(UserManager<AppUser> userManager,
            SignInManager<AppUser> signInManager)
        {
            Usermgr = userManager;
            SignInmgr = signInManager;
        }

        public async Task<IActionResult> Register()
        {

            var Person = new AppUser();
            Person.UserName = "username1";
            Person.Email = "[email protected]";
            Person.FirstName = "Firstname1";
            Person.LastName = "chees123";

            IdentityResult result = await Usermgr.CreateAsync(Person, "Password");

            if (result.Succeeded)
            {
                ViewBag.Message = "Account was succesfully created";

            }
            else
            {
                ViewBag.Message = "Something went wrong";
            }
return View();
        }
}

 IdentiyAppContext:

 

public class IdentityAppContext : IdentityDbContext<AppUser,AppRole, int>

{
    public IdentityAppContext(DbContextOptions<IdentityAppContext> options)
        : base(options)
    {

    }

}

 AppUser:

 

public class AppUser : IdentityUser<int>

{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

 Approle is empty at the moment:

public class AppRole : IdentityRole<int> //Identity calm
{

}

 Register view page: 

@{
    ViewData["Title"] = "Register";
}

<h2>Register</h2>
<p>@ViewBag.Message</p>
<div>
    <a asp-controller="Account" asp-action="Login">Login</a>
</div>

 it does not add to the database and i keep geting the message : "Something went wrong" (from the viewbag)
