Remarks

ObjectKeyFrame is an abstract class that defines Object value type key frames for DiscreteObjectKeyFrame. To animate an Object with key frames, you define a ObjectAnimationUsingKeyFrames animation, and populate its KeyFrames property with one or more DiscreteObjectKeyFrame elements that define the key frames.
