如何在EventAggregator中支持持久化？
我在 Prism 中使用 EventAggregator，我希望事件被持久化，这意味着当客户端订阅某个事件时，聚合器会发布之前错过的事件给客户端。有办法支持吗？
我知道这听起来更像是消息队列之类的东西。但系统已经与EventAggregator紧密耦合，因此我希望这个框架可以让我有选择地保留一些事件而不需要太多修改。
I am using EventAggregator in Prism, and I want the events persisted, which means when a client subscribes a certain event, the aggregator published the previous events that missed to the client. Is there a way to support this?
I know this sounds more like a message queue or something. But the system has already heavily coupled with EventAggregator thus I want this framework can allow me to selectively persist some events without too much modification.

以下文章讨论了“存储并转发”EventAggregator 实现，这听起来非常适合您的场景，即客户端能够赶上他们可能错过的事件：

The following article discusses a "store and forward" EventAggregator implementation which sounds like an excellent match for your scenario i.e. clients being able to catch up with events they may have missed:
