Debug Classic ASP in Visual Studio

If you don't mind running Visual Studio with admin privileges (or already do), then you can also try the following:

 

1. Use the "File -> Open Web Site..." command to open the site (under the "Local IIS" section).
2. From the Solution Explorer, open the files you want to debug and set breakpoints.
3. Start the debugger by selecting the "Debug -> Attach to Process..." menu item.

4. Select the "w3wp.exe" process.
