I want to set the background color of the application bar blue.how can i do it in xamarin.forms? Do I have to write the native code for the same how to do that?
I found the answer of my question myself.
In the native windows phone 8.1 app in MainPage.xaml
write the following code:
<Page.BottomAppBar>
<CommandBar Background="#0073b5" Foreground="White">
</CommandBar>
</Page.BottomAppBar>
