Is it possible to Serialize Objects in the ArcGIS Runtime SDK for WPF? I thought this should have worked but it does not. SimpleMarkerSymbol simpleMarkerSymbol = new SimpleMarkerSymbol() { Color = new SolidColorBrush(Colors.Red), Size = 10, Style = SimpleMarkerSymbol.SimpleMarkerStyle.Circle }; using (TextWriter textWriter = new StreamWriter(@c:\temp\test.xml)) { XmlSerializer xmlSerializer = new XmlSerializer(simpleMarkerSymbol.GetType()); xmlSerializer.Serialize(textWriter, simpleMarkerSymbol); }
