VS 2005, like its predessor, does not allow debugging for classic ASP pages, by default. This forces you to attach the ASP worker process (w3wp.exe). Follow these 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).
