Important

On May 21, 2024, Microsoft announced that Bing Maps for Enterprise and its API will be discontinued. Azure Maps will be a single unified enterprise mapping platform available from Microsoft.

To obtain and display map data from Azure Maps, we implemented the following providers:

• AzureMapDataProvider
• AzureSearchDataProvider
• AzureRouteDataProvider
• AzureGeocodeDataProvider
• AzureTrafficIncidentDataProvider
• AzureRouteIsochroneDataProvider

For information on how to migrate your app from Bing Maps to Azure Maps, see the following help topic: DevExpress Map Control for WPF: Migrate from Bing Maps to Azure Maps.

If you already have a Bing Maps for Enterprise license, you can keep using the current API. You must transition to the new API by June 30, 2025 (for free/basic licenses) or June 30, 2028 (for enterprise licenses). New licenses will no longer be available after June 30, 2025. Bing Maps will not work with our map controls without a license after that date.

• Create a InformationLayer object and add it to the MapControl.Layers collection. Assign the BingSearchDataProvider object to the InformationLayer.DataProvider property.
• Handle the BingSearchDataProvider.SearchCompleted event. In the event handler, implement the request result processing.
