Do we still need the IdentityConverter in .net 4.0? I seem to remember reading somewhere about some changes in WPF that would negate the need for this converter.
I believe you are right. If I remember correctly, there's a new binding property you can set in the binding expression to get the desired behavior.
My understanding is that they weren't going to fix the issue outright, because that could cause backward compat issues. So instead they added some property you can set to tell binding to do the right thing.
(obviously I lost track of the details of that issue, or I'd have a more definite/detailed answer...)
I found a previous post with a link
Looks like this is taken care of with System.ComponentModel.INotifyPropertyChanged
Oh good - so they did take the breaking change - kudos for them then!
