Getting lots of these

DEP0900: Failed to unregister application "49861f9e-48d3-45c0-b6a8-f591ad6d2010_1.0.0.1_x64__9zz4h110yvjzm". [0x80073CFA] 

Unsure why. Impossible to uninstall existing appx that match this app ID.

On 3.x, on WinUI, the LibVLC object is built using string parameters retrieved from an initialized VideoView (see the plan WinUI sample code). Will have to re-work the code to handle this in the MAUI sample for WinUI support.

Have you tried to unregister the app manually?
In a powershell: Get-AppxPackage *49861f9e-48d3-45c0-b6a8-f591ad6d2010*
Then Remove-AppxPackage -Package full package name, in my case the full name is: 49861f9e-48d3-45c0-b6a8-f591ad6d2010_1.0.0.1_x64__9zz4h110yvjzm

Progress. Need to check that 267bf18 doesn't break other UI frameworks.

Without 267bf18, there are errors like

With it, though, our windows video view initialization logic is broken since OnApplyTemplate never gets called. Reworking this view hierarchy would likely be a breaking change, for Uno, UWP and WinUI.
