Binding observable collection of custom markers

[Rjuken Developments]

Hello syncfusion team,

I'm trying to bind a collection of custom markers to the Markers property of the SfMaps.

But it throws me an error :

 Binding: System.Collections.ObjectModel.ObservableCollection`1[Project.Core.Models.WeatherMarker] can not be converted to type 'System.Collections.ObjectModel.ObservableCollection`1[Syncfusion.SfMaps.XForms.MapMarker]' 

Well, I don't understand because using  the same marker class but w/o binding works. Is it bindable ? 

Marker class is pretty simple : 

   public class WeatherMarker : MapMarker

    {

        public string LottieAnimation { get; set; }

    }

    private ObservableCollection _weatherMarkers;

        public ObservableCollection WeatherMarkers

        {

            get => _weatherMarkers;

            set => SetProperty(ref _weatherMarkers, value);

        }

 < maps:SfMaps  x:Name="sfmap" EnablePanning="False" EnableZooming="False" BackgroundColor="Transparent" >

                < maps:SfMaps.Layers >

                    < maps:ShapeFileLayer x:Name="ShapeLayer" Uri="FRA_adm0.shp" MarkerTemplate="{Binding MarkerDataTemplate}" Markers="{Binding WeatherMarkers}" >

                        < maps:ShapeFileLayer.ShapeSettings >

                            < maps:ShapeSetting  ShapeFill="{StaticResource PrimaryColorOne}" ShapeStroke="white" ShapeStrokeThickness="2" >

                            < /maps:ShapeSetting >

                        < /maps:ShapeFileLayer.ShapeSettings >

                    < /maps:ShapeFileLayer >

                < /maps:SfMaps.Layers >

            < /maps:SfMaps >

Regards.

Okay so I found out what's going on.

I have to type my ObservableCollection to MapMarker and not WeatherMarker.  

    private ObservableCollection< MapMarker > _weatherMarkers;

        public ObservableCollection< MapMarker > WeatherMarkers

        {

            get => _weatherMarkers;

            set => SetProperty(ref _weatherMarkers, value);

        }

Instead of : 

    private ObservableCollection< WeatherMarker > _weatherMarkers;

        public ObservableCollection< WeatherMarker > WeatherMarkers

        {

            get => _weatherMarkers;

            set => SetProperty(ref _weatherMarkers, value);

        }

It should work with WeatherMarker as it derives from MapMarker. Anyway, working now.
