Thank you!
In general, it works, but if the animation has been paused, then you need to call the StopAnimation () method before StartAnimation ();

In another case, a frame will jump.

Code:

if (_assimpAnimationController.IsAnimationPaused)
{
    // Have to stop for starting from required frame
    _assimpAnimationController.StopAnimation();
    Debug.WriteLine(_assimpAnimationController.CurrentFrameNumber);
    Debug.WriteLine(AnimationSlider.Value);
    _assimpAnimationController.FrameNumberOffset = AnimationSlider.Value;
}
