应用界面

使用最少的工作量/代码，可以通过视图轻松读取/绑定的 Wrapper Over 模型.

Wrapper Over Model which is easily readable/bindable by View using minimum Effort/Code.

1. IDataErrorInfo - 应该进入 ViewModel
2. INotifyPropertyChanged - 应该进入 ViewModel.必要时也可以进入模型(但不推荐)
3. 公共属性 - 是的，模型当然应该拥有它们.

1. IDataErrorInfo - Should go into ViewModel
2. INotifyPropertyChanged - Should go into ViewModel. Could also go in the Model if necessary (But not recommended)
3. Public Properties - Yes of course a Model should have them.
