Can't find out how to use Keyed() registration

[rumyancevpavel]

The documentation page says that i can register multiple types implementing the same interface using Keyed() registration extension. But it seems missing in 1.16.9...
Am I missing something?

I’m just another user, but here’s what I found:

Looks like the docs got a bit ahead of themselves—Keyed() didn’t make it into the 1.16.9 build. From the commit history, the code was merged earlier, but the actual release got held up while they finished off some test work.

The good news: v1.17.0 just dropped and Keyed() is now in the public API. Update to the latest package and you should be good to go.

Keyed() isn’t in v1.16.9. It was added in v1.17.0. Update the package, then use Keyed() on registration and [Key(...)] (or Resolve<T>(key)) on resolve.

Example (enum keys):

public enum WeaponType { Primary, Secondary }

builder.Register<IWeapon, Sword>(Lifetime.Singleton).Keyed(WeaponType.Primary);
builder.Register<IWeapon, Bow>(Lifetime.Singleton).Keyed(WeaponType.Secondary);

// Constructor injection
public class Combat
{
    public Combat([Inject, Key(WeaponType.Primary)] IWeapon primaryWeapon) { /* ... */ }
}

// Manual resolve
var sword = lifetimeScope.Container.Resolve<IWeapon>(WeaponType.Primary);
