Parameter injection works only with methods for MonoBehaviour

[nikolay-vrjam]

Here is a MonoBehaviour with single parameter

public class VenueTestStarterController : MonoBehaviour, IStartable
    {
        public enum StartType
        {
            Active,
            Passive
        }

        [Inject] private StartType _startType; // This does NOT work

        // [Inject]  // This Works
        // private void Inject(StartType sType)
        // {
        //     _startType = sType;
        // }

        public void Start()
        {
            Debug.Log($"starttype={_startType}");
        }
    }

and this is a scope configuration

    protected override void Configure(IContainerBuilder builder)
        {
            builder.RegisterComponentOnNewGameObject<VenueTestStarterController>(Lifetime.Scoped,
                nameof(VenueTestStarterController)).WithParameter(VenueTestStarterController.StartType.Passive);
            builder.RegisterBuildCallback(resolver =>
            {
                resolver.Resolve<VenueTestStarterController>();
            });
        }

Injection only works when it happens through method (commented in the first snipped), otherwise, it shows following error

"you must use method injection to inject them with dependencies."
More info: njecting into MonoBehaviours

Should .WithParameter() be exclusive to Construction Methods? Maybe there's an argument that they should be supported with all Injection types.
