问题描述
原本应该放入模型的东西也可以进入视图模型，即公共属性，IDataErroInfo和INotifyPropertyChanged，那么实际上应该放入模型中什么?
The things which are supposed to go into the Model are also allowed to go into the View-Model i.e. Public Properties, IDataErroInfo and INotifyPropertyChanged, then what should actually go into the model?
推荐答案
模型
Business Data + Business Logic + Business Rules
查看
Application UI
ViewModel
Wrapper Over Model which is ealily readable/bindable by View
using minimum Effort/Code.
1) IDataErrorInfo -应该进入ViewModel
2) INotifyPropertyChanged -应该进入ViewModel和Model(如果需要，不建议用于型号)
3) Public Properties -是的，当然Model应该有它们.
1) IDataErrorInfo - Should go into ViewModel
2) INotifyPropertyChanged - Should go into ViewModel, and Model (if needed, not recommended for Model)
3) Public Properties- Yes of course a Model should have them.
