Bing Maps Web Control SDK retirement

Bing Maps Web Control SDK is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Web Control SDK until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type. 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 example loads 1,000 random locations into a heat map that are within the initial view of a loaded map.

<!DOCTYPE html>

<head>
    <title></title>
    <meta charset="utf-8" />
	<script type='text/javascript'>
    function GetMap() {
        var map = new Microsoft.Maps.Map('#myMap', {
            credentials: ‘Your Bing Maps Key’
        });

        //Generate a 1,000 random locations that are within the bounds of the map view.
        var locs = Microsoft.Maps.TestDataGenerator.getLocations(1000, map.getBounds());

        //Load the HeatMap module.
        Microsoft.Maps.loadModule('Microsoft.Maps.HeatMap', function () {
            var heatmap = new Microsoft.Maps.HeatMapLayer(locs);
            map.layers.insert(heatmap);
        });
    }
    </script>
    <script type='text/javascript' src='http://www.bing.com/api/maps/mapcontrol?callback=GetMap' async defer></script>

Here is what this random heat map looks like when the map is loaded over Redmond, WA.
