Hi Peter,
We will be having UWP support for all of our Xamarin.Forms controls in Volume 1, 2016 release which is estimated to rollout in the next week. Along with our existing controls, following controls will also be added.
1. Carosual
2. Rotator
3. NumericUpdown
4. Presentation library (non-UI)
We will let you know once it is rolled out. We appreciate your patience until then.
Regards,
Nijamudeen M.
