Visual Studio 2000 Community Technology Preview (Whidbey) and IIS
I have seen one other blog about this so far from Brian Noyes. I did however manage to get mine working side by side with automatic debugging for vs.net 2003. I suggest before you whidbey that you make a backup copy of your metabase using MetaEdit. Unfortunately, I didn't.
I uninstalled IIS, rebooted, reinstalled IIS, rebooted. Visual Studio 2003 still didn't work for automatic debugging. After the reinstall I ran aspnet_regiis -i against the 1.1 framework. Now automatic debugging is working like a champ.
