Answer 1

There are many ways in which you can do this.
1) Using device-family either in code behind or as another xaml
See this tutorial you will get the idea.
2) Now if you want you can also use Viewstates along with Adaptive triggers which is simple but these will work even when desktop app is resized to avoid that you will have to create device specific triggers. check out WindowsStateTriggers
