I have the following code: 

AddHandler aX.Completed, AddressOf AnimationCompleted

...

Private Sub AnimationCompleted(sender As Object, e As EventArgs)

      Dim ac As AnimationClock = sender
      Dim aX As DoubleAnimationUsingPath = ac.Timeline

      RemoveHandler aX.Completed, AddressOf AnimationCompleted

End Sub

Throws:

Specified value of type 'System.Windows.Media.Animation.DoubleAnimationUsingPath' must have IsFrozen set to false to modify.

How can I remove the event handler if the object is frozen? My concern is that if the event handler is not removed the animation object will not be properly garbage collected.

    Removing the event handler is not necessary. See [this answer](http://stackoverflow.com/a/298276/1136211). – Clemens Apr 13 '16 at 10:13
  • Is this the case in WPF? I know there are instances in WPF if you don't remove the event handler of a control then the control is not removed even though it is no longer in the Window. – apc Apr 13 '16 at 10:27
  • We're talking about a regular .NET event here, so the answer should be applicable. – Clemens Apr 13 '16 at 10:29
