I'm trying to draw a custom Live Tile in my Windows Universal App. Specifically, a circle. I understand that I can provide a bitmap, but I'm not having any luck.
I've tried to follow examples online, but without any luck. Like this: How do I create a WP8 Live Tile with a custom layout?
It uses a WriteableBitmap's .Render() - but when I try to do the same, it seems that .Render() does not exist.
Can someone give me an example of how to create a bitmap that will work in a Universal App that will run on Windows Phone 8 (and ideally the Windows 8 + Windows 10 + Windows Phone 10)?
