[WPF 4.5] Subscribing to an event using a markup extension

It's been a while since I last wrote about markup extensions… The release of Visual Studio 11 Developer Preview, which introduces a number of new features to WPF, just gave me a reason to play with them again. The feature I'm going to discuss here is perhaps not the most impressive, but it fills in a gap of the previous versions: the support of markup extensions for events. Until now, it was possible to use a markup extension in XAML to assign a value to a property, but we couldn't do the same to subscribe to an event.
