Scott Guthrie posted about a hotfix available for VS 2005 to fix a performance issue when debugging ASP.NET applications by pressing F5 to start debugging.

This has been one of my pet peeves using ASP.NET debugging, the startup time is horrible.  I originally thought it was some of the third-party controls I used and when I couldn’t fix it, just assumed I would have to live with it.  This has been over 3 years of use.

I hadn’t realized this was a known bug by Microsoft and finding this information today is like found money.  Yes, I am very happy indeed.
