wpf - How do I detect when a removable disk is inserted using C#?

Question

I'm just concerned about Windows, so there's no need to go into esoterica about Mono compatibility or anything like that.

I should also add that the app that I'm writing is WPF, and I'd prefer to avoid taking a dependency on System.Windows.Forms if at all possible.
