Continuing from my last post on macOS, there is now a MediaElement renderer for WPF in InTheHand.Forms 2.0.2019.913. The native control in WPF is a lot more limited and is missing two big features – no system provided transport controls, and no support for HTTPS sources. The latter is an unfortunate limitation though it looks as though this is being fixed for WPF on .NET Core.
A possible workaround for these limitations is to have the WPF renderer use the UWP MediaPlayerElement when running on Windows 10 1903 and above. This is currently available as a WPF control as part of the Windows Community Toolkit.
