✅ How to make static field required to use from interface?

I have this interface:

public interface IEventProcessor
{
    public static IReadOnlyCollection<string> HandledEvents { get; } = [];
}

public interface IEventProcessor
{
    public static IReadOnlyCollection<string> HandledEvents { get; } = [];
}

public interface IEventProcessor
{
    public static IReadOnlyCollection<string> HandledEvents { get; } = [];
}

public interface IEventProcessor
{
    public static IReadOnlyCollection<string> HandledEvents { get; } = [];
}

HandledEvents

HandledEvents

HandledEvents

HandledEvents is static because I can easily read values from it using reflection and without

Activator.CreateInstance

Activator.CreateInstance

Activator.CreateInstance

Processor example:

public sealed class FlightEventProcessor(JsonSerializerOptions serializerOptions): IEventProcessor
{
    public static string[] HandledEvents => ["FlightAdded", "FlightUpdated"];
}

public sealed class FlightEventProcessor(JsonSerializerOptions serializerOptions): IEventProcessor
{
    public static string[] HandledEvents => ["FlightAdded", "FlightUpdated"];
}

public sealed class FlightEventProcessor(JsonSerializerOptions serializerOptions): IEventProcessor
{
    public static string[] HandledEvents => ["FlightAdded", "FlightUpdated"];
}

public sealed class FlightEventProcessor(JsonSerializerOptions serializerOptions): IEventProcessor
{
    public static string[] HandledEvents => ["FlightAdded", "FlightUpdated"];
}

the main problem H

andledEvents

andledEvents

andledEvents

andledEvents can be easily removed from

FlightEventProcessor

FlightEventProcessor

FlightEventProcessor

FlightEventProcessor and nothing will happens. compilator allows me to not implement this array inside every classes that inherit

IEventProcessor
