How can we implement global exception handling?

[aueda]

The section "Places where errors may occur" shows all the places where an exception might be thrown, but the recommended resolution is wrapping the code with local try-catch statements. While we can add local try-catch to all the places, we might miss a few places and an unhandled exception might freeze the application.

Is there a way to implement a global exception handling, so we can catch any unhandled exception, like the ASP.NET custom errors? It would be useful to have a global exception handling so we can cover any unexpected exception while delivering a user-friendly page.
