WPF progress bars are conceptually the same as Windows progress bars; however, a very noticeable difference is that using standard coding techniques, the WPF Progress Bars do not update correctly while the application is processing.
Here i am going to give an example of animated progress bar in wpf. for this example i am using double animation in ellipse.
