Apologies for the noobish question, and I did try to search but couldn't find the right answer (or didn't search properly).
Currently have an app developed in a windows desktop environment because it gives us access to deeper features of the PC such as serial port comms etc. that the normal metro environment wouldn't allow. We're currently developing the UI based on metroUI so we can run it on an 8.1 touchscreen (metroUI looks good, gives us a touch-screen experience with PC features) but we have no intention of putting it on the marketplace.
Just wanted to confirm if this is in fact doable, and we can have this desktop application with a metro UI? Or is my noobishness meaning I'm overlooking some technical feasibility that makes it impossible?
