Microsoft deprecated the UWP MapControl and Windows Maps platform APIs on April 8, 2025. Existing apps may keep working, but Microsoft says the features will not be updated and may not be available in future Windows versions. Its migration guidance pointed developers toward an Azure Maps-based replacement within one year—around April 8, 2026. That was a migration target, not a confirmed date when every existing app would stop working. As of September 2026, treat the old mapping stack as an unsupported dependency and plan a replacement rather than relying on an unannounced shutdown date.

What Microsoft deprecated

The change applies to the Windows-specific developer mapping stack, not simply the consumer Windows Maps app. It includes the XAML MapControl in Windows.UI.Xaml.Controls.Maps and mapping and location services in Windows.Services.Maps. Depending on your application, that can cover map display, annotations and camera behavior, geocoding and reverse geocoding, route calculation, authentication through a MapServiceToken, and offline-map-related functionality. See Microsoft’s deprecated Windows client features, its migration resources, and the Maps and location overview.

These APIs relied on Bing Maps services. Microsoft has directed developers toward Azure Maps as Bing Maps for Enterprise is unified with Azure Maps. That does not make Azure Maps a drop-in replacement: it can require a new map surface, service calls, authentication design, and offline strategy.

Dates: deprecation is not a universal shutdown date

Date or milestone What it means
April 8, 2025 Microsoft’s deprecation date for the Windows UWP Map control and Windows Maps platform APIs.
Approximately April 8, 2026 One year after the deprecation notice, the planning target implied by Microsoft’s advice to move solutions using the control within one year. It is not evidence that all installations stop working on that day.
July 2025 A separate milestone for the consumer Windows Maps app. Do not treat it as the shutdown date for developer APIs.

Microsoft says deprecated features may continue to function but will not be updated and may not be available in future Windows versions. The cited Windows client guidance does not give one definitive date when every UWP app will lose map rendering or service results. A map that still loads today is working by compatibility, not by a continuing support commitment. The distinct product timelines are described in Microsoft’s deprecated-feature resources.

Who needs to act?

Audit any UWP application that displays a map or calls a location service. This includes line-of-business, kiosk, field-service, fleet, logistics, and asset-tracking apps, as well as apps that use geocoding or routing in the background without showing a map. Windows 10 or Windows 11 targeting, MSIX packaging, or a still-valid legacy key does not remove the dependency.

Search source, XAML, project files, packages, and configuration for these names:

Windows.UI.Xaml.Controls.Maps
Windows.Services.Maps
MapControl
MapLocationFinder
MapRouteFinder
MapService
MapManager
MapServiceToken
Geopoint
GeoboundingBox
MapIcon
MapPolyline
MapPolygon
MapTileSource
OfflineMapPackage
xmlns:maps
maps:MapControl
ServiceToken

Check shared UWP libraries, NuGet wrappers, resource dictionaries, and background jobs too. The MapControl reference and Windows.Services.Maps reference help identify the API surface.

Why an app can fail in stages

  • Build and platform risk: The APIs may remain in an SDK for now, but are deprecated and may not be present in future Windows versions.
  • Service risk: A working control does not guarantee that its backend will continue returning tiles, routes, or geocoding results.
  • Credential and operations risk: A stored key does not guarantee future service access, and quotas, agreements, and authentication can change independently of the UI.
  • Product risk: A blank or partially loaded map can leave users unable to complete a critical workflow even when the rest of the app installs and runs.

Choose a replacement based on requirements

Azure Maps is Microsoft’s stated destination for developers moving away from the old Windows mapping stack. Consider it first if your organization already operates on Azure, but verify that its selected services and map control meet your application’s needs. Microsoft’s migration resources link to Azure Maps documentation and samples; start with the Azure Maps documentation.

Other providers may fit better depending on the workload. Google Maps Platform is worth evaluating when its places, search, routing, or map ecosystem suits the product (Google Maps Platform). Mapbox is a candidate for customized map styling and web-map experiences (Mapbox). Esri is often relevant to GIS-heavy, government, utilities, and asset-management applications (ArcGIS Developers). HERE merits evaluation for fleet and logistics routing (HERE). Each requires its own review of licensing, data policies, Windows integration, coverage, and offline capabilities.

Open-source or self-hosted components, such as OpenStreetMap data and MapLibre, can offer greater control, but they do not eliminate operating costs or responsibility for hosting, updates, routing, geocoding, reliability, and data licensing. See OpenStreetMap and MapLibre. Do not assume a public map-tile service is an unlimited production backend.

Plan a migration around features, not controls

Before selecting a provider, inventory the work the old stack performs. A visual replacement alone can miss important dependencies.

Area Questions to resolve
Map display Do you need road or aerial views, custom styling, pitch, rotation, or particular zoom behavior?
Interaction and overlays Which pins, shapes, labels, clustering, hit-testing, tile overlays, and selection behaviors must remain?
Camera and UI Which view changes, scene transitions, events, keyboard interactions, and accessibility behaviors matter?
Location services Do you need address search, autocomplete, forward or reverse geocoding, routing, traffic, or travel-time estimates?
Offline Must the map, search, or routing work without connectivity? How are offline data and updates handled?
Deployment and operations Which Windows versions and device types are supported? Are there proxy, firewall, regional-hosting, or network restrictions?
Governance What attribution, privacy, data-retention, telemetry, and regional requirements apply?

Pick an architecture that fits the app

  • Keep UWP and host a web map in WebView2: This can preserve much of the existing shell while replacing the map surface. It introduces a JavaScript/native bridge, WebView2 lifecycle and rendering considerations, and a need to test connectivity and offline behavior.
  • Move to WinUI 3 or another desktop framework: This may make sense if the application is already being modernized. Changing frameworks does not restore the deprecated UWP MapControl; you still need a mapping provider.
  • Replace mapping incrementally: For a large application, isolate rendering, geocoding, search, and routing behind provider-neutral interfaces, then replace each capability without rewriting unrelated business logic.

A simple boundary might look like this:

Application UI
     |
Map and location abstraction
     |
Provider adapter
     |
Azure Maps or another selected provider

Keep the contract focused on your product’s needs rather than mirroring the old API names. Map display, geocoding, routing, and search can be separate services, allowing each to evolve independently.

Authentication, privacy, and cost need redesign too

The legacy stack used a maps authentication key or MapServiceToken; Microsoft’s authentication-key guidance describes the old model. A replacement provider has different credential and usage rules. Do not put unrestricted, long-lived secrets in a desktop package or source code. Follow the provider’s recommended client authentication, restrict credentials where supported, consider a backend token broker for sensitive operations, and plan key rotation, quota alerts, and monitoring.

Review attribution and data-use terms before release. Map providers can differ in caching permissions, retention rules, regional endpoints, billing units, and usage policies. Build a cost estimate from expected map loads and service requests, then confirm current rates and terms on the provider’s official pricing pages; do not assume a provider is cheaper based on a feature list.

Offline use is a separate decision

The old platform included offline map package functionality, including APIs associated with MapManager. Do not assume an Azure Maps control or another cloud mapping service reproduces that behavior. Establish whether users need an offline basemap, offline routing, cached route geometry, or only access to business data while disconnected. Then verify the chosen provider’s supported offline model, storage and update process, caching rights, coverage, and behavior when cached data expires.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

For field service, emergency response, transport, and industrial deployments, disconnected operation may be the deciding requirement. A cloud-only API may be unsuitable unless the application has an acceptable fallback or a separately supported offline design.

Validate the replacement before retiring the old path

Compare the new system against real product workflows, not only a successful map load. A provider can return different address formatting, coordinates, place identifiers, route geometry, and traffic estimates from the old service. For a mission-critical app, run both paths in parallel where practical and review the differences with users.

  • Test map initialization, pan, zoom, rotation, pitch, annotations, selection, route lines, and overlays.
  • Test geocoding and reverse geocoding with representative addresses, ambiguous results, localization, and empty-result handling.
  • Test routing with real waypoints, applicable travel modes, timeouts, no-route responses, and traffic requirements.
  • Test high-DPI displays, accessibility, keyboard use, and screen readers where relevant.
  • Simulate invalid credentials, throttling (including HTTP 429), quota exhaustion, service outage, slow responses, partial tile loads, and network loss.
  • Test restricted networks, proxies, TLS inspection, firewall allowlists, DNS, WebView2 availability, and regional endpoint access.
  • Measure performance, memory, network use, battery impact, availability, and cost at realistic usage volumes.

Define a useful fallback rather than leaving users with a blank map: show cached business data, retain a last-known route where appropriate, provide a text address or directions view, queue eligible requests, or explain clearly that the map is unavailable.

Migration checklist

  1. Find every dependency: Search code, XAML, packages, configuration, and background services for the listed APIs and credentials.
  2. Record the current behavior: Capture screens and workflows, supported devices, required Windows versions, regional needs, and performance baselines.
  3. Classify requirements: Separate rendering, search, geocoding, routing, offline, accessibility, and compliance needs.
  4. Select the provider and architecture: Decide whether the app will use a web surface, REST services, a suitable SDK, or a self-hosted design.
  5. Build provider boundaries: Keep mapping concerns separate from business logic so testing and future provider changes are manageable.
  6. Implement credentials and operations: Apply least privilege, quotas, monitoring, rotation, and privacy review.
  7. Run an acceptance matrix: Validate normal behavior, outages, network restrictions, offline scenarios, and regional coverage.
  8. Roll out with a fallback: Use staged deployment where possible, monitor errors and usage, and retire the legacy path only after the replacement meets operational requirements.

The key decision is not whether the old control renders on a particular PC today. It is whether your application can tolerate an unsupported platform dependency with uncertain future availability. Microsoft’s one-year migration guidance has passed; choose and validate a replacement on your own requirements, without treating that guidance as a universal shutdown date.
