In arcgis online I can change the symbol for all the features in the layer to be a png image.
But I want every feature be a different symbol. Most like it the picture in user profile. So I will have the image url from the user information.
I see In this example Symbols and renderers—ArcGIS Runtime SDK for .NET | ArcGIS for Developers you can create a pictureMarkerSym then use it to create a Graphic and add it to an Overlays.
var graphic = new Graphic(location, pictureMarkerSym);
But right now I only have a FeatureLayer?
Do I need create an extra Overlay Layer to show the symbol of each feature? Or I can change the Feature symbol as in ArcGis Online?
