You have a WinMain function there. The Microsoft linker sees that 
as an indication that you are writing a Windows gui application 
and thus suppresses the console window.

Inside your program, you can always call the AllocConsole() 
function to pop up a console and attach it:

So a potential fix for you to just stick

debug AllocConsole();

right inside your WinMain before doing anything else.


Or my preference is to just never write WinMain in D. Just write 
a normal D main and use -L/subsystem:windows when you don't want 
the console (note: on 64 bit using the subsystem with normal 
main(), you also need to pass `-L/entry:mainCRTStartup.` to dmd 
so it uses the right entry point), and allow the defaults if you 
do want it.
