Adding markers and navigation line

Markers can be added to the layers of Bing Maps by setting the corresponding location’s coordinates of latitude and longitude using MarkerSettings. Navigation lines can be added on top of an Bing Maps layer for highlighting a path among various places by setting the corresponding location’s coordinates of latitude and longitude in the NavigationLineSettings.
