        public static implicit operator T(Setting<TNamed, T> setting)

        {
            return new Setting<TNamed, T>() {Value = value };
        }
    }
}

If you want to keep type safety:

public class QuestionConfigurationSetting : ISetting

public interface ISetting {}

public class Setting<TNamed, T> where TNamed : ISetting { ... }
