barra di avanzamento in WPF

Question

Voglio creare un ProgressBar che assomiglia a un cilindro in WPF, proprio come nell'immagine seguente (qui è fatto in WinForm):

Qualcuno mi può mostrare come fare o forse mi dai un trucco? Grazie

si deve modificare Modello di progressbar per this.See Template di Progressbar

cura Template/Stile

<Window.Resources> 
    <Style TargetType="{x:Type ProgressBar}">

Visitate questa pagina Web. Utilizzano il modulo di Windows ma la logica può essere applicata in wpf.
