Debugging Outlook Add-ins doesn't work if you have disabled add-ins

In the feedback section of my post on a Hello World Outlook Add-in, Ron Cicotte mentioned a debugging problem he was having, and finally tracked it down after having to use an MSDN support incident. The problem is that if you have any disabled Outlook add-ins, VS will not stop at any breakpoints in other add-ins. The fix is to reenable all add-ins. I thought this was worth capturing in a top level blog entry in case anyone else runs into it. One of the values of blogs is that they provide a great repositories of useful information that can be found via search engines.
