@enigmatico it used the .Net framework of that era if I recall correctly.
I know ow they used to offer a stand alone application (they might still) that you could purchase that allowed Enterprise customers to used their Office GUI and add backend code. I see it all the time in applications like Epic used by the hospital system for all of my doctors. I can’t remember what the heck it was called.
Is this what you’re after, or am I misunderstanding? 😎
