IsDirty implementation for WPF

Question

Hello

Does anyone have an IsDirty implementation they find particularly useful? Ideally I'd like to support Undo but not have to lug a framework like CSLA in. I'd also prefer an implementation that favors composition over inheritance.

I'm working with WPF with a ViewModel slant right now (INotifyPropertyChanged). The last SO question I've seen is a bit old and doesn't fully address what I'm asking in this one.

Cheers,
Berryl
