Custom ASP.NET Identity 2.0 UserStore - Is implementing all interfaces required?

Question

I\'ve created a custom IUserStore for my application. I\'ve implemented the interfaces I need,

   IUserStore,
           


        

Answer 1

I had the same problem and I don't want to implement the IUserTwoFactorStore just to say that I don't implement it. But I also don't want to go back and muck around if I end up wanting to implement it (which I anticipate I will). So what I consider a future proof (and reusable) solution would be: (inspired by @gjsduarte's answer)

public class SafeUserManager : UserManager
{
    public override Task GetTwoFactorEnabledAsync(TKey userId)
    {
        return Store is IUserTwoFactorStore
            ? base.GetTwoFactorEnabledAsync(userId)
            : Task.FromResult(false);
    }
}

It would probably be a good idea to do the same for the other Get[feature]EnabledAsync(TKey userId) methods.
