Extending IdentityRole and IdentityUser

Question

I am using ASPNet Identity to implement security in my web application.

There is a requirements where in, I need to extend the IdentityRole and IdentityUser.

Here is my code to extend the IdentityUser.

public class ApplicationUser : IdentityUser
{
    public virtual User  User { get; set; }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("name=CoreContext")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<IdentityUser>()
            .ToTable("AspNetUsers");
        modelBuilder.Entity<ApplicationUser>()
            .ToTable("AspNetUsers");
    }
}

My only problem is the IdentityRole

To extend User , Update your ApplicationUser class(located in IdentityModels.cs) to

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> 
        GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager
            .CreateIdentityAsync(this, 
                DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }

    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

    // Use a sensible display name for views:
    [Display(Name = "Postal Code")]
    public string PostalCode { get; set; }

}

To Extend Role , Create a class ApplicationRole.cs

public class ApplicationRole : IdentityRole
{
    public ApplicationRole() : base() { }
    public ApplicationRole(string name) : base(name) { }
    public string Description { get; set; }
}

and Add the class inside IdentityConfig.cs file :

public class ApplicationRoleManager : RoleManager<ApplicationRole>
{
    public ApplicationRoleManager(
        IRoleStore<ApplicationRole,string> roleStore)
        : base(roleStore)
    {
    }
    public static ApplicationRoleManager Create(
        IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(
            new RoleStore<ApplicationRole>(context.Get<ApplicationDbContext>()));
    }
}

Now clear the old database, Run the application and register a user. It will create 3 more fields(Address,City,State) in AspNetUsers table and one more field(Description) into AspNetRoles table. That's it.

You can inherit from IdentityRole in your application the same way that you do your IdentityUser. Why do you need to extend IdentityRole? Please take a look at the following article which explains in detail what you are trying to do http://typecastexception.com/post/2014/02/13/ASPNET-MVC-5-Identity-Extending-and-Modifying-Roles.aspx
