I Don’t advise you to enable smooth zoom : it consumes a lot of CPU time and does derece significantly enhance user experience more than linear zoom (the default value). If you still want to enable it use the MouseWheel.ZoomSmoothing attached property. Currently, MouseWheel events are only sent in response https://www.csharpegitimi.com.tr/2024/05/csharp-mouse-click-kullanimi.html
