I am using MediaElement in my program.

XML

<MediaElement x:Name="media" Source="MyVideo.mp4" Height="480" Width="640" HorizontalAlignment="Left" VerticalAlignment="Top" LoadedBehavior="Manual" Stretch="Fill" />

In various articles I see the possibility of using the PosterSource property in this element.

XML

<MediaElement PosterSource="imageUri" />

This property is missing in my media. Where could there be a mistake?

P.S. I use Visual Studio Enterprise 2015. The version of .NET Framework is 4.7.2.

What I have tried:

I'm looking for a missing item.

We have already found the answer. This function is available only in UWP applications.

~~According to MediaElement.PosterSource Property (Windows.UI.Xaml.Controls) - Windows UWP applications | Microsoft Docs[^] it is present in that version of Windows 10.~~

[edit]
That refers to UWP only. Microsoft docs could be a bit easier to navigate sometimes.

The list "Applies to WinRT" contains Build 18362. I have OS build 18362.836. Could this be a problem?

My apologies, I was looking in the list at left. It appears that this feature is not available in the non UWP versions.

OK. I'm understood, thank you!
