Clustering in ArcGis Runtime SDK for .NET

and  this  answer

you will have  a  calss  named the PointClusterer

but  for  showing  your location and  getting  result  from this  class ,  you should  be  some  things

you have to convert your  location to  the WebMercator

for  that  use  this  part  of  code

GraphicsOverlay clusterLayer = new GraphicsOverlay();
PointClusterer clusterer=new PointClusterer();
GraphicCollection collection = new GraphicCollection();

foreach (var items in AllPoint)
            {

                MapPoint campsitePointz = new MapPoint(items.gpsY, items.gpsX, SpatialReferences.Wgs84);

                var newpoint = GeometryEngine.Project(campsitePointz, SpatialReferences.WebMercator);


                collection.Add(new Graphic(newpoint));


          }
 clusterer.Graphics = collection;
 clusterLayer.GraphicsSource = clusterer;
 mapview.GraphicsOverlays.Add(clusterLayer);

this  line

var newpoint = GeometryEngine.Project(campsitePointz, SpatialReferences.WebMercator);

will convert your  location to the  WebMercator .

the Geometry is  exsit  in the  Esri.ArcGISRuntime.Geometry namespace.

and  now the  points will be appear  in the proper  locations in the map.
