Error catch in Whidbey

I forgot yesterday t mention the cool way you can catch an error exception in Whidbey at debugging time.

You indicate which error you want to stop on, and when you debug, Whidbey stops and show you the line where you have the issue with a nice bubble and soem advices on how to fix the error.

Neat but one question. Does this system can apply to any errors ? I think about the type of errors like Internal Network Connection  (mostly linked to SQL connections and the pool).
Can we will have a way to extend the list to some new errors ?
