Is it safe to flag an asynchronous PropertyChangedCallback property?

Question

I have a dependency property in the class, let's call it "SomethingControl":

public static readonly DependencyProperty SomethingProperty = DependencyProperty.Register("Something", typeof(Something), typeof(SomethingControl), new UIPropertyMetadata(SomethingGotSet));

And I defined a callback method that is passed to the UIPropertyMetadata constructor as asynchronous:

 private async static void SomethingGotSet(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var control = (SomethingControl)d;
        if (control != null)
        {
            control.SomeOtherProperty = await AsynchronousMethodCall();
        }
    }

Is it safe to do this? Will this cause a dead end or problems in the user interface thread? I tested it and everything seems to be fine, but I cannot find anything in the MSDN documentation using asynchronous property callback methods like this.

From what you show us, it looks completely safe.

PropertyChangedCallback (void). "Fire-And-Forget".
