How to hit a breakpoint in classic ASP script running in Visual Studio 2015?

I am trying to debug a classic ASP application (written in VBScript) using Visual Studio 2015.

The page which is throwing the error is structured as follows :

 <% 
 :
 :
 class MyFile
 :
 :
 899 someObj.Open sSQL, connect
 :
 :
 %>

The page throws an error at the line above.

COM Error Number : -2147217900 (0x80040E14) 
File Name : /includes/MyFile.Class.asp 
Line Number : 899 
Brief Description : Invalid column name 'Column'.

But I cannot debug this. I tried the following

• Putting "Stop" before the line -> Does not work. It just does not stop !
  • Debug breakpoint is not hit -> Tried running it from within Visual Studio
  • Debug breakpoint is not hit -> Tried running the page separately and attaching the VS debugger to IISExpress.

Any suggestions ? Is inline script debugging (this is not within javascript) supported at all ?

Select your site in the IIS Management tool, Doubleclick "ASP" in the main window. Set "Send Errors To Browser" to True, enable client-side and server-side debugging as well.

If you have Visual Studio installed, and add a "STOP" instruction anywhere in the vbscript code, you should be able to select Visual Studio as the debugger.
