Like its predessor, VS 2005 does not allow you to debug classic ASP pages by default. Instead, you have to manually attach the ASP worker process (w3wp.exe). Follow these simple steps:
- Enable ASP debugging on the server.
- Open the classic ASP Page in VS 2005.
- Set breakpoint.
- View page in browser or run without debugging.
- Debug | Attach to Process.
- Attach the IIS ASP worker process (w3wp.exe).
