Answer 1

There's a detailed explanation and an implementation here. It was written mainly for .NET 3.5 SP1 but it will still work in 4.0.

The primary target of this implementation is when the "real" list exists longer than the bindable view of it (eg. if it is bound in a window that the user can open and close). If the lifetimes are the other way around (eg. you're updating the list from a background worker that runs only when the window is open), then there are some simpler designs available.
