扩展优化方案（基于.NET 9企业开发框架）：

1. 响应式数据改造：

// 使用CommunityToolkit.Mvvm的ObservableProperty 
[ObservableProperty]
[NotifyPropertyChangedFor(nameof(AgeGroup))]
private Person? _currentPerson;

1. 全球化数据处理：

Name = LocalizationService.GetString(
    key: "Person.DefaultName", 
    fallback: "Michael Jackson"
);

1. 数据验证层：

public class Person : ValidatableModel 
{
    [Range(18, 100, ErrorMessage = "AGE_VALIDATION_ERROR")]
    public int Age { get; set; }
    
    [Required(ErrorMessage = "OCCUPATION_REQUIRED")]
    [MaxLength(50)]
    public string Occupation { get; set; }
}
