Catch-all error handling on application level?

Question

I have a WPF form with a couple of buttons, and for each button I have error handling code:

try {bla bla} 
catch(Exception e){
  more bla
}

You can subscribe to AppDomain.UnhandledException event (see MSDN) to accomplish this. Ideally, this happens when bootstrapping your application. You can find the AppDomain you're executing in via AppDomain.Current.
