I am learning WPF / Silverlight and saw in an MS vidcast that it is now recommended to use RoutedEventArgs over EventArgs; although it didn't say exactly why.
I have a win forms app that uses interfaces for "widgets" in an attempt to not be tied to a specific display technology (in Presenters / ViewModels), so if my IButton Click event now needs to take the RoutedEventArgs now I guess it isn't as useful.
Can someone please explain if I should switch to RoutedEventArgs in all cases and why?
As an aside, does anyone else have experience / opinions about using interface widgets as I'm describing them?
