Current Behavior

Upon exiting a page that has a MediaElement, although calling the DisconnectHandler as recommended, MediaElement does not get removed.

Expected Behavior

MediaElement should be garbage collected.

Steps To Reproduce

1. Open and run the solution from the reproduction repository
2. Click the button to go to the second page where the memory element lives
3. Click the back button to go to the main page
4. Check gcdump vie heapview and search for MediaElement

Anything else?

Hi @brminnick, I've upgraded Media Element to 5.0.0, but I still see the same problem. Is there anything else I need to be doing to make sure the media element is disconnected correctly?

The reproduction repo now includes a sample with the upgraded media element.

Sorry if I am missing something obvious.

Handler disconnect is done automatically by Maui now. If you want more info: https://learn.microsoft.com/en-us/dotnet/maui/whats-new/dotnet-9?view=net-maui-9.0. You can control it yourself if you set the handler disconnect policy.

Example:

 <toolkit:MediaElement
     x:Name="MediaElement"
     HandlerProperties.DisconnectPolicy="Manual"
     Source="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"/>

The above code will let you control it manually. It is up to you if you want it to work this way now. By default it will work automatically in the background.
