FreezableCollection<T>.Clone Method ()
Creates a modifiable clone of this FreezableCollection<T> and its contents, making deep copies. If this collection (or its contents) has animated dependency properties, the property’s base value is copied, not its current animated value.
Assembly: PresentationCore (in PresentationCore.dll)
This method shadows the inherited Animatable.Clone method with a strongly typed implementation for convenience.
