In my situation I am running on Vista. I had the same issue not being able to debug ASP.NET apps, and read your resolution. During my attempt to make the changes you suggested, VS told me that in order to switch to using IIS, I had to run VS wiith Administrator privileges, so I changed set my VS shortcut to ‘Run as Administrator’. Leaving VS as is (continuion to run under the VD Development Server, not changing to use IIS), I was able to debug my application. Vista can be a real PITA !!!

Just for debugging the application you dont have to switch to IIS. That can be done with VS development engine itself. I think its VS2005 feature more than Vista.
I feel creating an application is better because,
It helps in simulating the production environment,
The library output is just one DLL.
Relative reference to images works the same way in development as well as production.
