Timeline.Clone Method ()
Creates a modifiable clone of this Timeline, making deep copies of this object's values.
Assembly: PresentationCore (in PresentationCore.dll)
This method is used to produce modifiable copies of frozen Freezable objects (or any Freezable object). For convenience, this method shadows the inherited version with a strongly typed implementation.
For more information, see Freezable.Clone.
When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.
