How to set rules on AspNetRules?

Question

Hello Guys,
I am bit confused on how to set rules as "Admin" "client" "normal user" on AspNetRules
What I have done is:

1. I created a MVC project

2. Made a connection string with my  local db sql server management studio

3. I executed the application, and created the first user, in order to create all the tables on my db. As you can see below
 

What I have tried to on Controllers --> AccountController.cs

 

//

// POST: /Account/Register

[HttpPost]

[AllowAnonymous]

[ValidateAntiForgeryToken]

public async Task Register(RegisterViewModel model)

{

if (!ModelState.IsValid) return View(model);

var user = new ApplicationUser() { UserName = model.UserName };

var result = await UserManager.CreateAsync(user, model.Password);

if (result.Succeeded)

{

try

{

using (var dal = new DALEF.WebShopEntities())

{

dal.Client.Add(

new DALEF.Client{

CLI_Nom = model.Nom,

CLI_Prenom = model.Prenom,

CLI_Civilite = model.Civilite,

CLI_Email = model.Email,

CLI_Adresse = model.Adresse,

CLI_CodePostal = model.CodePostal,

CLI_Ville = model.Ville,

CLI_Telephone = model.Telephone,

CLI_AspUser_Id = user.Id

});

dal.SaveChanges();

}

}

catch (Exception)

{

// client n'est pas ajouté delete l'asp user créé

ModelState.AddModelError("", "Echec création client, veuillez réessayer");

return View(model);

}

//await UserManager.AddToRoleAsync(user.Id, "client");

await SignInAsync(user, isPersistent:false);

return RedirectToAction("Index", "Home");

}

else

{

AddErrors(result);

}

// If we got this far, something failed, redisplay form

return View(model);

}

 

 

But when I create a new user, I receive an error:

When I check the db, i see that the user is created, but not the rule. 

 

 How can I create rules? Just very simple rules as "Admin" or "Normal user", in order to create the [Authorize] for the Views.

Thanks in advance.
