Is there any kind of event or a way that would allow me to catch all exceptions that were not handled?

Basically, my application will have the usual Try Catch blocks around code that can crash but what about code that shouldn't normally crash that doesn't have the blocks? I'd rather not put EVERYTHING in Try Catch blocks (that would be quite time consuming).

Is there a way to basically catch an exception that isn't encapsulated in a Try Catch block?
