How to handle them may vary, depending on what you're doing and what you're looking to accomplish, but WPF comes with two very easy solutions that you can use: The Observable Collection and the INotify Property Changed interface.

So you can easily bind against the data context to display various members of your data object Whereas it was really hard to display complex data in a List Box with Win Forms, its super easy with WPF.

The following example shows a List Box with a list of Dependency Property Info instances bound to it.

This will make the Add and Delete button work, but it won't do anything for the "Change name" button, because the change will happen on the bound data object itself and not the source list - the second step will handle that scenario though.

The second step is to let our custom User class implement the INotify Property Changed interface.
