Extending ASP.NET Identity Roles: IdentityRole is not part of the model for the current context

Question

I\'m trying to use the new ASP.NET Identity in my MVC5 application, specifically I\'m trying to integrate ASP.NET Identity into an existing database. I\'ve already read the

I solved with a different way. First I splited in two different Projects and Contexts. My project that Handle the Identity has this context:

    public class ApplicationDbContext : IdentityDbContext, IDisposable
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

This is my ApplicationUser:

public class ApplicationUser : IdentityUser
    {
        //Put here the extra properties that Identity does not handle
        [Required]
        [MaxLength(150)]
        public string Nome { get; set; }

        public async Task GenerateUserIdentityAsync(UserManager manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }
    }

And my ApplicationUserManager looks like this:

public class ApplicationUserManager : UserManager
    {
        public ApplicationUserManager(IUserStore store)
            : base(store)
        {
            //Setting validator to user name
            UserValidator = new UserValidator(this)
            {
                AllowOnlyAlphanumericUserNames = false,
                RequireUniqueEmail = true
            };

            //Validation Logic and Password complexity 
            PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireNonLetterOrDigit = false,
                RequireDigit = false,
                RequireLowercase = false,
                RequireUppercase = false,
            };

            //Lockout
            UserLockoutEnabledByDefault = true;
            DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
            MaxFailedAccessAttemptsBeforeLockout = 5;

            // Providers de Two Factor Autentication
            RegisterTwoFactorProvider("Código via SMS", new PhoneNumberTokenProvider
            {
                MessageFormat = "Seu código de segurança é: {0}"
            });

            RegisterTwoFactorProvider("Código via E-mail", new EmailTokenProvider
            {
                Subject = "Código de Segurança",
                BodyFormat = "Seu código de segurança é: {0}"
            });

            //Email service
            EmailService = new EmailService();

            // Definindo a classe de serviço de SMS
            SmsService = new SmsService();

            var provider = new DpapiDataProtectionProvider("Braian");
            var dataProtector = provider.Create("ASP.NET Identity");

            UserTokenProvider = new DataProtectorTokenProvider(dataProtector);

        }
    }

I hope that this helps someone. This solution was from this article: Eduardo Pires - But it is in Portuguese
