Cannot debugging asp.net on IIS7 by attaching process w3wp

asp.netdebuggingiis-7w3wp

I have a asp.net website in VS2008 which I have pre-compiled in local directory which is virtual directory for IIS 7（http://machinename:83）

when i
1. launch http://machinename:83/
2. VS2008–>debug–>Attach to Process..–>select w3wp.exe
3. set the breakpoint in code in VS2008
4. run app

while i found it cannot go to the breakpoint. (i m sure the breakpoint must be run)

anybody can help me on this?

What you're doing should work, but you can try this, which is frequently used to debug Windows services upon startup:

System.Diagnostics.Debugger.Launch();

Just put it on the line where you want to start debugging, and the OS will prompt you to attach.
