WPF Binding to IDictionary<int,MyType>.Values Doesn't Respond to Property Changes?

databinding

I am binding a ListView a property that essentially wraps the Values collection (ICollection) on a generic dictionary.

When the values in the dictionary change, I call OnNotifyPropertyChanged(property). I don't see the updates on the screen, with no binding errors.

When I change the property getter to return the Linq extension dictionary.Values.ToList(), without changing the signature of the property (ICollection) it works with no problem.

Any reason why the Values collection bind and notify properly without projecting to an IList<>?
