Use AppBar as resource on multiple pages in Universal Windows App - xaml

Question

I would like to use a AppBar on multiple pages as a resource.
I found an MSDN document (link) but it's for Windows Phone.
Does anyone know if this is even possible for Universal Apps?
This is how my App.xaml looks like now:
<Application.Resources>
<AppBar x:Key="GlobalBar" ClosedDisplayMode="Minimal">
<!--Controls....-->
</AppBar>
</Application.Resources>
But how do I implement this on, let's say, MainPage.xaml?

Answer 1

The fastest and easiest way to do this is to have a page with the AppBar and a Main Frame.
Create a RootPage.
Add an Appbar.
Add a Frame and name it
something(ex rootFrame)
In the constructor or OnNavigatedTo of
rootPage navigate the rootFrame to your MainPage.
Now you have an AppBar in all pages. In the pages you can use this.Frame.Navigate(...) to navigate. In rootPage where your AppBar is you can use rootFrame.Navigate(...)

Answer 2

Sadly you can't do exactly as you want....But you can implement it with a different approach. Use a single master page - add Frame and a single AppBar. The Frame will take care of Page Navigation. I will also suggest you to use commandBar instead of AppBar in UWP apps.
You can use it in MainPage.xaml as -
<Page
x:Class="App2.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:App2"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Page.BottomAppBar>
<AppBar>
</AppBar>
</Page.BottomAppBar>
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<!--Your Code-->
</Grid>
