How to add roles to users in ASP.NET with OWIN - asp.net

Question

I'm new in ASP.NET and I'm making a simple project to practice. I started with a simple MVC project without authentication because it adds many code that I didn't understand.
But now I want to add a membership to my sistem so I followed this guide:
http://benfoster.io/blog/aspnet-identity-stripped-bare-mvc-part-1
http://benfoster.io/blog/aspnet-identity-stripped-bare-mvc-part-2
But I don't know where I can add a role to the user entity..
My Startup class is this:
public class Startup
{
public static Func<UserManager<Usuario>> UserManagerFactory { get; private set; }
public void Configuration(IAppBuilder app)
{
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = "ApplicationCookie"
});
UserManagerFactory = () =>
{
var usermanager = new UserManager<Usuario>(new UserStore<Usuario>(new Vetpet3Context()));
usermanager.UserValidator = new UserValidator<Usuario>(usermanager)
{
AllowOnlyAlphanumericUserNames = false
};
return usermanager;
};
}
}
And I'm creating (for now) my users with this Action:
[HttpPost]
public async Task<ActionResult> Register(RegisterModel model)
{
if (!ModelState.IsValid)
{
return View();
}
var user = new Usuario
{
UserName=model.correo,
correo = model.correo
};
var result = await userManager.CreateAsync(user, model.password);
if (result.Succeeded)
{
await SignIn(user);
return RedirectToAction("index", "Home");
}
foreach (var error in result.Errors)
{
ModelState.AddModelError("", error);
}
return View();
}
So everything works fine at this point, but I need to add different roles to the users , and this is the question, how I implement this part? I've read many guides but everyone does different things and I'm not sure how to add a role to my new users and how to claim these roles when they log in

Answer 1

to add role to the user after he successfully register :
if (result.Succeeded)
{
var roleResult = userManager.AddToRole(user.Id, "Admin");
await SignIn(user);
return RedirectToAction("index", "Home");
}
to check if the user in role :
userManager.IsInRole(user.Id, "Admin");
or even simpler in any ASP.NET MVC [Authorized] controller :
User.IsInRole("roleName");
