First of all VBScript is an interpreted language and does not need to be compiled.
But yes, you can debug your VBScript file inside Visual Studio.
Under "Tools / External Tools" you have to register the Windows Script Host (CScript.exe or WScript.exe) once with some startup parameters (to make it available in the Tools menu):
Title: VBScript Debug
Command: C:WindowsSystem32cscript.exe
Arguments: //nologo //X $(ItemPath)
Initial directory: $(ItemDir)
Check "Use Output window"
Hit the OK button
Then, just open the file you want to debug with Visual Studio (via File --> Open --> File...)
In order to start the debugger, just click "Tools / VBScript Debug".
The VS JIT debugger asks you, wich debugger you want to use. Just select your *.vbs file and click Yes.
Note:
This answer is still valid and works with Visual Studio 2019.
