Overview
Azure Maps (.NET)
Azure Maps SDK for .NET packages Microsoft's location services - geocoding, routing, map rendering, IP geolocation, and weather - into five separate NuGet libraries with typed C# clients. It supports subscription-key, Entra ID, and SAS authentication, with working code for geocoding, route matrices, isochrones, map tiles, and weather lookups. Use it when a .NET app needs first-party Azure Maps clients instead of raw REST calls - for address search, routing, static map images, or weather data - and an Azure Maps account with valid credentials already exists.
What it does
This skill wraps the Azure Maps SDK for .NET, exposing five focused client libraries: Azure.Maps.Search for geocoding and reverse geocoding, Azure.Maps.Routing for directions and route matrices, Azure.Maps.Rendering for map tiles and static images, Azure.Maps.Geolocation for IP-to-country lookups, and Azure.Maps.Weather for current conditions, forecasts, and severe weather alerts. Each area ships as its own NuGet package, currently prerelease betas such as Azure.Maps.Search v2.0.0-beta.5 and Azure.Maps.Routing v1.0.0-beta.4, installed independently depending on which capability the application needs.
dotnet add package Azure.Maps.Search --prerelease
Authentication supports three paths: a subscription key via AzureKeyCredential, Microsoft Entra ID via DefaultAzureCredential (the guide's recommended path for production), or a Shared Access Signature token generated through Azure.ResourceManager.Maps.
When to use - and when NOT to
Reach for this skill when a .NET application needs address search, turn-by-turn directions, route or isochrone calculations, map tile rendering, IP-based geolocation, or weather data, and wants it through typed Azure SDK clients rather than raw REST calls. It is not a map-display UI toolkit - it covers the data and rendering APIs, not an interactive map component - and it assumes an existing Azure Maps account, since every code path needs a subscription key, Entra ID client ID, or SAS token to authenticate.
Inputs and outputs
Inputs vary by client. MapsSearchClient.GetGeocoding() takes a free-text address string and returns a GeocodingResponse with coordinates, formatted address, and confidence score; GetReverseGeocoding() takes a GeoPosition (longitude/latitude) and returns the address at that point. MapsRoutingClient.GetDirections() takes an ordered list of GeoPosition waypoints and returns RouteDirections with distance, duration, and per-leg point data; GetRouteMatrix()/GetImmediateRouteMatrix() take origin/destination position lists (synchronous capped at 100 combinations, asynchronous up to 700) and return a distance/duration matrix. MapsRenderingClient.GetMapTile() takes a tile index (X/Y/zoom) and returns an image Stream. MapsGeolocationClient.GetCountryCode() takes an IPAddress and returns an ISO country code. MapsWeatherClient.GetCurrentWeatherConditions() takes a GeoPosition and returns temperature, phrase, and humidity. All calls throw RequestFailedException on failure, with ex.Status distinguishing invalid parameters (400), authentication failure (401), and rate limiting (429), for which the guide recommends exponential backoff.
Integrations
Built on Azure.Identity for Entra ID authentication (DefaultAzureCredential), and on Azure.ResourceManager.Maps for account-level operations such as generating SAS tokens through ArmClient/MapsAccountResource. The packages compose independently - a project can install only Azure.Maps.Weather, for instance, without pulling in routing or rendering.
Who it's for
.NET developers building location-aware features - address lookup, delivery or routing logic, static map generation, IP-based geo-targeting, or weather-driven logic - who want first-party Azure SDK clients with Entra ID support rather than hand-rolled REST calls against the Azure Maps API.
