Attach Debugger to IIS instance
In Visual Studio:
- Click "Debug" from the menu bar
- Click "Attach to Process"
- Check the "Show processes from all users" checkbox in the bottom left corner
- Select aspnet_wp.exe, w3p.exe, or w3wp.exe from the process list
- Click "Attach"
Just to clarify Jimmie R. Houts answer…
If you want to debug the web application VS and IIS you can do the following:
- Host the site inside IIS (virtual directory etc).
Then in VS2005 do this:
- Right Click on Web Project → Properties → Start options → Use Custom Server → Base URL → Enter Site Address as Hosted in IIS.
- Hit F5 and you will be able to Debug your code
Same works for VS 2008 also.
I'm running Windows 7 with IIS Version 7.5 and I also needed to tick the "Show processes from all users" and "Show processes in all sessions" boxes - at the bottom of the "Attach to Process" dialog.
Also I had put my app in a specific App Pool which means you can then see it labeled against the w3wp.exe.
