[UWP][XAML] Blank app with only a MediaPlayerElement fails XAML parsing

Question

Hi all,

After learning that MediaElement is deprecated in favor of MediaPlayerElement, I started transitioning to the new control in an app I'm working on. However, while working on my Azure VM with build 1607 (AU), I get XAML parsing errors. To try and verify the issue, I made a brand new, empty UWP app with only a MediaPlayerElement, and the XAML still won't parse. I get a COM exception about a class not being registered (REGDB_E_CLASSNOTREG) in InitializeComponent(). Any ideas for how to fix this?

Hi InLocoAbsentia,

It’s a known issue. You could use Franklin’s workaround “setting the Source property from code behind” on this thread: https://social.msdn.microsoft.com/Forums/Windowsserver/en-US/520cc74a-159a-4ea5-b7ad-2b5d08288beb/uwpmediaplayerelement-doesnt-work?forum=wpdevelop

This is helpful, but it wasn't exactly the problem I was having. It seems to have resolved itself after a restart of the VM, however.
