Xamarin transparent background image not showing as transparent (Grey and white)-CodePudding

I am new to xamarin forms. I am trying to display an image with "Transparent background" (Grey and white) but this is how it show on the application.
I am using PNG file for the picture as I saw the other thread commenting on PNG/JPG files but it did not work.
I also try with opacity and backgroundcolor="Transparent" but it did not work either.
The image is random transparent background image got from google.
Any help is appreciated! Thanks.

Picture of the application

<StackLayout BackgroundColor="OrangeRed">
    <Image Source="icon11.png" Aspect="AspectFit" />
</StackLayout>

As Shaw mentioned in the comment, I made a blunder on the transparent background PNG files.
I tested with a transparent background xamarin logo from pre-built xamarin form pages and it worked.
Conclusion for my case: Double check if the picture actually has transparent background.

Detail Info:
The picture I used and shown above does not actually have transparent background, one can check when open it from your PC (It will shows the white and grey boxes).
