Application Debugging is disabled in Visual Studio 2012 on Classic ASP Debugging

Question

I'd like to debug Classic ASP website at Visual Studio 2012 with IIS Express. Hence, I attached the iisexpress.exe in VS 2012, but it shows Application Debugging is disabled. What could be a problem ? Do I want to enable any configuration settings?

Answer 1

First of all you need to enable server side debugging of classic ASP script. Do this by running the following commands:

"C:\Program Files (x86)\IIS Express\appcmd.exe" set config "[YOUR_SITE_NAME]" -section:system.webServer/asp /appAllowClientDebug:"True" /appAllowDebugging:"True"  /commit:apphost

Where [YOUR_SITE_NAME] is the name of your website. You can find this name by opening up:

%USERPROFILE%\Documents\IISExpress\config\applicationhost.config 

...and searching for your site.

Next, start an IIS Express instance from the command line:

"C:\Program Files (x86)\IIS Express\iisexpress.exe" /config:c:\users\kevin\Documents\IISExpress\config\applicationhost.config /site:"[YOUR_SITE_NAME]" /apppool:"Clr2IntegratedAppPool"

Again, [YOUR_SITE_NAME] is the name of your IIS Express website.

Then attach Visual Studio 2012's debugger and set a breakpoint in the script you wish to debug. Browse to your site/script and your should see the breakpoint light up:

Go to IIS-->ASP-->Debugging properties -->enable client and server side debugging
