Azure Maps (.NET)

Azure Maps SDK for .NET providing location-based services: geocoding, routing, rendering, geolocation, and weather.

Installation

# Search (geocoding, reverse geocoding)
dotnet add package Azure.Maps.Search --prerelease

# Routing (directions, route matrix)
dotnet add package Azure.Maps.Routing --prerelease

# Rendering (map tiles, static images)
dotnet add package Azure.Maps.Rendering --prerelease

# Geolocation (IP to location)
dotnet add package Azure.Maps.Geolocation --prerelease

# Weather
dotnet add package Azure.Maps.Weather --prerelease

# Resource Management (account management, SAS tokens)
dotnet add package Azure.ResourceManager.Maps --prerelease

# Required for authentication
dotnet add package Azure.Identity

Current Versions:

• Azure.Maps.Search: v2.0.0-beta.5
• Azure.Maps.Routing: v1.0.0-beta.4
• Azure.Maps.Rendering: v2.0.0-beta.1
• Azure.Maps.Geolocation: v1.0.0-beta.3
• Azure.ResourceManager.Maps: v1.1.0-beta.2

Environment Variables

AZURE_MAPS_SUBSCRIPTION_KEY=<your-subscription-key>
AZURE_MAPS_CLIENT_ID=<your-client-id>  # For Entra ID auth

Authentication

Subscription Key (Shared Key)

using Azure;
using Azure.Maps.Search;

var subscriptionKey = Environment.GetEnvironmentVariable("AZURE_MAPS_SUBSCRIPTION_KEY");
var credential = new AzureKeyCredential(subscriptionKey);

var client = new MapsSearchClient(credential);

Microsoft Entra ID (Recommended for Production)

using Azure.Identity;
using Azure.Maps.Search;

var credential = new DefaultAzureCredential();
var clientId = Environment.GetEnvironmentVariable("AZURE_MAPS_CLIENT_ID");

var client = new MapsSearchClient(credential, clientId);

Shared Access Signature (SAS)

using Azure;
using Azure.Core;
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Maps;
using Azure.ResourceManager.Maps.Models;
using Azure.Maps.Search;

// Authenticate with Azure Resource Manager
ArmClient armClient = new ArmClient(new DefaultAzureCredential());

// Get Maps account resource
ResourceIdentifier mapsAccountResourceId = MapsAccountResource.CreateResourceIdentifier(
    subscriptionId, resourceGroupName, accountName);
MapsAccountResource mapsAccount = armClient.GetMapsAccountResource(mapsAccountResourceId);

// Generate SAS token
MapsAccountSasContent sasContent = new MapsAccountSasContent(
    MapsSigningKey.PrimaryKey, 
    principalId, 
    maxRatePerSecond: 500, 
    start: DateTime.UtcNow.ToString("O"), 
    expiry: DateTime.UtcNow.AddDays(1).ToString("O"));

Response<MapsAccountSasToken> sas = mapsAccount.GetSas(sasContent);

// Create client with SAS token
var sasCredential = new AzureSasCredential(sas.Value.AccountSasToken);
var client = new MapsSearchClient(sasCredential);

Core Workflows

1. Geocoding (Address to Coordinates)

using Azure;
using Azure.Maps.Search;

var credential = new AzureKeyCredential(subscriptionKey);
var client = new MapsSearchClient(credential);

Response<GeocodingResponse> result = client.GetGeocoding("1 Microsoft Way, Redmond, WA 98052");

foreach (var feature in result.Value.Features)
{
    Console.WriteLine($"Coordinates: {string.Join(",", feature.Geometry.Coordinates)}");
    Console.WriteLine($"Address: {feature.Properties.Address.FormattedAddress}");
