        public int UserId { get; set; }
        public virtual UserProfile UserProfiles { get; set; }      
    }

Why are you doing this? you do not need to define this yourself. if you use AccountController, and if you use WebSecurity Role, this table is created for you in the SimpleMemberShipInitializer filter. and you just need to use the built-in functions provided to you by SimpleMembership.
