Endgame Viable

Recently I learned that you can debug into the Microsoft .NET Framework. Other than idle curiousity, I can’t think of any reason why I’d want to do that, except to confirm or deny that there is a bug in the Framework. This suggests to me that Microsoft is basically trying to outsource analysis of framework bugs onto the community, and I’m guessing there won’t be too many payments for that service forthcoming. Is this supposed to inspire me to have more confidence in Microsoft?
