One way to achieve the desired result is to use the map's VisualizationLayer
and it's ItemTemplate
This approach is demonstrated in the attached project with the ItemTemplate from one of our demos.
Another approach is instead of using ItemTemplate and ItemsSource to try the PointData object and add it in the Items collection of the VisualizationLayer. The default visual of the PointData object is similar to the one demonstrated in the image attached in your last reply.
For more information about the VisualizationLayer
you can check the Map Shape Data
