Remarks

This interface allows you to create your own easing functions by taking normalized time (value 0 through 1) and passing back your desired value.

IEasingFunction is the property type of several EasingFunction properties on key-frame types, and therefore it is the interface that technically enables the XAML usage for those properties, not the EasingFunctionBase type. For details, see EasingColorKeyFrame, EasingDoubleKeyFrame, or EasingPointKeyFrame.
