<ControlTemplate> <Ellipse Fill="{Binding Symbol.Color}" Stroke="Black" /> </ControlTemplate>
What is this IJsonSerializable interface for? Do you know if I need to extend that as well in my project for it to work properly?
Also, you mentioned this other SimpleMarkerSymbol class in ESRI.ArcGIS.Client.FeatureService.Symbols, what is the difference between that class and the one I am using?
