MetroProgressBar

The MetroProgressBar is an alternative progress bar with a different indeterminate style. Instead of creating a normal ProgressBar use:

<mah:MetroProgressBar Width="250"
 Margin="4"
 Maximum="100"
 Minimum="0"
 Value="42" />

or

<mah:MetroProgressBar Width="250"
 Margin="4"
 IsIndeterminate="True" />

Its indeterminate state looks like a ProgressRing but not circular.
