Using an ObservableCollection in a service

I have a few projects. One of the projects will be deployed as a Windows Service. An other project is a WPF application. There are a few other applications managing some data (of external hardware or the database). The data-lists are almost all ObservableCollection's.

I've read around a bit and it seems like ObservableCollection is only really ment for the UI layer (the WPF application, in my case). Is that correct? Would I be better of using events (PropertyChanged) in the service/datamanager layers?

In a service, usually all objects should only live as long as it takes to process the current request, correct? So, normally you wouldn't need change notification at all in the service layer, since the service would perform all changes to the model itself. For the next request, the required objects would be read again from the backing store.
