I'm trying to develop my first window phone app with Titanium. I have installed de wp 8.1 sdk and created a 'hello world' test app. I am able to launch this app in a windows phone 8 emulator (I launch it from appcelerator studio).

So far so good. Now I want to test the app on a device.
My windows phone has the windows phone 10 operating system.

My question is:
Is it possible to run an app which is developed for wp8 on a wp10 device. I expect the device to be backwards compatible but maybe it's not??

When I try to launch the ap on the device (from studio) I get this error:
