Using VS (instead of WinDbg) to debug application startup

This is another one of those things that I forget all the time, so I'm posting here as a way of remembering (and because it's incredibly useful if, like me, you find windbg somewhat opaque).

It's very convenient to be able to set this registry key and break into your application on startup, regardless of how it is launched, and even more convenient that you can use VS. Cheers!
