我手动创建一些类的LINQ到SQL设计并期待在xx.designer.cs时，文件中的类不实现INotifyPropertyChanged接口。

I've manually created some classes in the Linq-to-sql designer and when looking in the xx.designer.cs file the class doesn't implement INotifyPropertyChanged interface.

这工作，如果我通过从服务器资源管理器拖放创建实体。

This works if I create the entity by dragging from the server explorer.

有谁知道这是为什么，如果我做错了什么，或者是在某个地方设置这在设计师。

Does anyone know why this is and if I am doing something wrong or if there is somewhere to set this up in the designer.

干杯。

推荐答案

它看起来像它，除非你标记的成员作为主键没有做到这一点。然后，它这样做。 presumably变化的跟踪是没有用的无主键...

It looks like it doesn't do this unless you mark a member as a primary key. Then it does this. Presumably change tracking is useless without a primary key...
