Icons, sometimes known as Points of Interest (POI), Pushpins, or Markers, are the primary method in the Bing Maps native controls to add a graphical image and text at a location within the map.
Icons also support a concept of flyouts. Flyouts are a type of lightweight menu that can show up when a user interacts with an icon. You can add your own user interface elements on top of a MapFlyout.
