How to restart WPF application after it has been updated using click-once, i need to start the new version!
There are a few ways but most don't work correctly, they end up reopening the old version.
It's going to sound crazy that WPF doesn't have a proper way to handle it (#fixwpf), but you'll need to reference System.Windows.Forms.dll
and call System.Windows.Forms.Application.Restart();
A quick search found Rob Relyea's post about the same thing (XAML, WPF Microsoft Guy) http://robrelyea.wordpress.com/2007/07/24/application-restart-for-wpf/
