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.

Answer 1

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

public class ApplicationUser : IdentityUser
{
    public async Task 
        GenerateUserIdentityAsync(UserManager 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
{
    public ApplicationRoleManager(
        IRoleStore roleStore)
        : base(roleStore)
    {
    }
    public static ApplicationRoleManager Create(
        IdentityFactoryOptions options, IOwinContext context)
    {
        return new ApplicationRoleManager(
            new RoleStore(context.Get()));
    }
}

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.
