How to implement an animated slider in WPF?

Question

WPF

It is necessary to create an analogue of a slider in a c # application. To create a similar design, it was advised to use WPF.
An interface element must be able to shift information within itself. I implemented this via enclosed in . The content was changed using the PageLeft() and PageRight( ) methods (so far, this is the only way I know how ... do not judge strictly). The problem is the lack of animation. Please tell me the best way to implement it.
