LineSymbolMarker is used for rendering a simple marker graphic on a SimpleLineSymbol. Markers can enhance the cartographic information of a line by providing additional visual cues about the associated feature.

If you are in a 3D SceneView use a LineSymbol3DLayer which has support for LineStyleMarker3D.
