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.

One of the most common types of searches done with a map is a nearby search, also known as a radial search. In the example an event handler is added to the maps viewchangeend event. When the map is panned or zoomed this event will trigger a query to the PointsOfInterest data source in Bing Spatial Data Services and will retrieve up to 25 gas stations that are within 25 kilometers of the center of the map. A filter will be used to limit the results to those that have an EntityTypeID value of 5540, which is the ID used for Gas Stations in this data source.

Running this code will load a map that displays the locations of gas stations. As you pan and zoom the map new data will be pulled in. Here is a screenshot of gas stations in Bellevue, WA.
