wpf-samples | Infragistics Ultimate UI for WPF product samples | Theme library

I can not find a working sample of a video playing in WPF.

The most obvious sample, that I'd expect to work, is in the official WPFSamples repo: https://github.com/microsoft/WPF-Samples/tree/master/Sample%20Applications/VideoViewerDemo

However, when I deploy and run this, I get no compile errors or runtime errors. However the video simply does not appear.

"Please can someone indicate what might be wrong with my approach on the configuration of running the official sample of the WPF MediaPlayer class?"

The specific code, as from the WPFSample repositiory is as follows:

In MainWindow.xaml:

Hello I tried to build an application using the WPF,.Netcore 3.0 and microsoft ribbon control library 4.0 and it's failed.

I need help or an example on the web. I did look at Microsoft WPF-Sample on GitHub but did not find a ribbon sample working on .netcore 3.0

MainWindow.Xaml

I am currently browsing WPF examples on this GitHub. This one is a simple application - it binds a textbox to a label. Whenever the textbox's text changes, the label is changed too via a data binding.

Now, I'm reading a StaticResource is evaluated the moment the XAML object is constructed and cannot be changed later, while a DynamicResource is evaluated each time it is accessed.

In this program, it would seem to me DynamicResources should be used, however only two StaticResources are present.

Here is what I'd deem the crucial code:

I found a custom routed command example form the Microsoft Examples, It works well.
