Search for comment in xaml <!-- HERE: Pointer is wrong direction --> and look image.
I use lates library build.I notice that "ArrowGaugeIndicator" direction have the same value -50 and show correct direction, but "MarkerGaugeIndicator" show wrong direction.

Hi Pet,

Thanks for the feedback. 
This is a bug in the marker indicator and it has been fixed. The fix will be available in the next official release.
Also you need to change your path figure in the marker template. It should be:

<Path Stroke="{StaticResource PhoneForegroun
    <Path.Data>
        <PathGeometry>
            <PathFigure StartPoint="10, 0"
                        IsClosed="True">
                <LineSegment Point="10,14"/>
                <LineSegment Point="0, 7"/>
            </PathFigure>
        </PathGeometry>
    </Path.Data>
</Path>

Write again if you have other questions.
Your Telerik points have been updated.
