I'm completely new to WPF. As far as I've read, WPF's…
I'd like to implement my own control for Windows Phone. The catch is, that I want to draw it myself - in regular WPF I'd simply override OnRender method and provide my own implementation. However, there is no OnRender method available on Windows…
