使用具有 POCO 支持的 Entity Framework 4 实现属性更改事件的最简洁、最有效的方法是什么？
为简单起见，开箱即用的 POCO 模板不包含 OnPropertyChanged 支持，那么在实体框架中向我的 POCO 对象实现属性更改事件的最简洁[且最有效]的方法是什么4、类似于标准的EF 4.0数据模型哪些会抛出这些事件？
我真的想要高性能的东西，我什至不介意属性发生了什么变化；当实体实例/对象具有任何已更改的属性时，我很高兴收到一个事件。
我最接近的猜测是实施一项策略 像这样进入生成我的 POCO 类的 POCO T4 模板 (.tt)，我是否走在正确的轨道上？但我只是想确保这是最常见的方法？这是否已作为标准 POCO 模板完成？

Seeing that the POCO template out-of-the-box does not include OnPropertyChanged support for simplicity, what would be the neatest [and most efficient] way to implement property changed events to my POCO objects within Entity Framework 4, similar to the standard EF 4.0 Data Model which throws these events?
I really want something with high performance, I don't even mind what property has changed; I would be happy to just receive an event when the entity instance/object has any property that has changed.
My closest guess would be to implement a strategy like this into the POCO T4 Template (.tt) which generates my POCO classes, would I be on the right track? However I just want to make sure this is the most common approach? Is this already done as a standard POCO template somewhere?

你实际上回答了你自己的问题。解决方法是修改 T4 模板并添加您需要的支持级别。如果您需要一些灵感，请检查实体设计器在不使用 T4 模板时生成的默认类或由自跟踪实体生成器（另一个 T4 模板）生成的类 - 他们还应该使用
OnPropertyChanged。You actually answered your own question. The way to go is modifying T4 template and add level of support you need. If you need some inspiration check default classes generated by entity designer when not using T4 templates or classes generated by Self-tracking entities generator (another T4 template) - they should also use
OnPropertyChanged.
