Analog of DependencyPropertyDescriptor (wpf) in Avalonia Ui?

Question

How do I implement the same behavior(wpf) in Avalonia?

var leftDescriptor= DependencyPropertyDescriptor.FromProperty(Canvas.LeftProperty, typeof(SomeObject));
    leftDescriptor.AddValueChanged(this, OnCanvasLeftChanged);

Answer 1

You can just subscribe to changes like this: Canvas.LeftProperty.Changed.Subscribe(OnCanvasLeftChanged);

Make sure to import the System namespace, otherwise the relevant extension method from System.ObservableExtensions won't be found by the compiler.
