Bing Maps Web Control SDK retirement

Bing Maps Web Control SDK is deprecated and has been retired for all free (Basic) account customers. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all enterprise account customers using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by June 30th, 2028. For detailed migration guidance, see Migrate from Bing Maps Web Control SDK and Migrate Bing Maps Enterprise applications to Azure Maps with GitHub Copilot.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

The following code creates a simple polygon that has a red outline and a semi-transparent green fill color, and has a stroke thickness of 2 pixels.

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta charset="utf-8" />
	<script type='text/javascript'>
    function GetMap() {
        var map = new Microsoft.Maps.Map('#myMap', {});

        var center = map.getCenter();

        //Create array of locations to form a ring.
        var exteriorRing = [
            center,
            new Microsoft.Maps.Location(center.latitude - 0.5, center.longitude - 1),
            new Microsoft.Maps.Location(center.latitude - 0.5, center.longitude + 1),
            center
        ];

        //Create a polygon
        var polygon = new Microsoft.Maps.Polygon(exteriorRing, {
            fillColor: 'rgba(0, 255, 0, 0.5)',
            strokeColor: 'red',
            strokeThickness: 2
        });

        //Add the polygon to map
        map.entities.push(polygon);
    }
    </script>
    <script type='text/javascript' src='http://www.bing.com/api/maps/mapcontrol?callback=GetMap&key=[YOUR_BING_MAPS_KEY]' async defer></script>
</head>
<body>
    <div id="myMap" style="position:relative;width:600px;height:400px;"></div>
</body>
</html>

Here is what this polygon would look like when zoomed out.
