Hi,
It seems that from some reason LineDashStyle does not take effect when used with FeatureLayerWpfDrawingOverlay. Lines are always drawn with solid line even if e.g LineDashStyle.DashDot is used in style. This can be re-produced e.g by changing LayerOverlay to FeatureLayerWpfDrawingOverlay in Render lines example on HowDol.
Is this intentional or a bug ?
Br, Simo
