Can I add multiple child elements to a frame in XAML?

Yes, you can add multiple child elements to a frame in XAML by placing them inside the frame’s content. For example:

XAML

<Frame CornerRadius="5" BorderColor="Black" 
  HasShadow="True">
        <StackLayout>
           		<Label  Text="Hello, World!" />
        		<Button Text="Click Me" />
        </StackLayout>    
   </Frame>
