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 code creates a polyline that is red in color, has a thickness of 3 pixels, and has a dash array where the stroke/gap sequence is "4, 4".

<!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
        var coords = [center, new Microsoft.Maps.Location(center.latitude + 1, center.longitude + 1)];

        //Create a polyline
        var line = new Microsoft.Maps.Polyline(coords, {
            strokeColor: 'red',
            strokeThickness: 3,
            strokeDashArray: [4, 4]
        });

        //Add the polyline to map
        map.entities.push(line);
    }
    </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 polyline would look like when zoomed out.
