I have an app which has navigation bar at the bottom. I'd like to keep that part of the page static - it would be 'base' for all other pages. I could add the exact same part of the code to every xaml page, however, I feel like initializing navigation bar on each page is waste of resources and time.
To make it more clear, below is an image of Facebook app (iPhone), pretty much same UI on Windows 10. Red bordered part of the UI never changes no matter what page you move to. For those using Facebook app you know that when you slide left/right only content in the middle (without red border) changes and slide animation is applied only to that part of the page.
That is basically what I'd like to achieve. Static part of the code that will initialize only once, stay visible on all pages, and no animations or page transitions would apply to it while switching between pages. I've been reading documentation and have not found any helpful information on how to achieve that.

Framecontrol and simply navigate in this Frame then. UWP is not HTML, the usage of frames is allowed here :) - sibbl
