What is the standard/recommended way for an app to display indicators that are media related like paused or muted etc? These could be buttons I suppose, I can a back button on a sample here that is a white circle with left arrow - how is this image being
associated with the button?
<Button x:Name="backButton" Margin="39,59,39,0" Command="{Binding NavigationHelper.GoBackCommand, ElementName=pageRoot}"
Style="{StaticResource NavigationBackButtonNormalStyle}"
VerticalAlignment="Top"
AutomationProperties.Name="Back"
AutomationProperties.AutomationId="BackButton"
AutomationProperties.ItemType="Navigation Button"/>
No image is specified here...
