Azure Maps Search client library for .NET

Azure Maps Search is a library that can query for locations, points of interests or search within a geometric area.

Getting started

Install the package

Install the client library for .NET with NuGet:

dotnet add package Azure.Maps.Search --prerelease


You must have an Azure subscription and Azure Maps account.

To create a new Azure Maps account, you can use the Azure Portal, Azure PowerShell, or the Azure CLI. Here's an example using the Azure CLI:

az maps account create --kind "Gen2" --account-name "myMapAccountName" --resource-group "<resource group>" --sku "G2"

Authenticate the client

There are 2 ways to authenticate the client: Shared key authentication and Azure AD.

Shared Key Authentication
  • Go to Azure Maps account > Authentication tab
  • Copy Primary Key or Secondary Key under Shared Key Authentication section
// Create a SearchClient that will authenticate through Subscription Key (Shared key)
AzureKeyCredential credential = new AzureKeyCredential("<My Subscription Key>");
MapsSearchClient client = new MapsSearchClient(credential);
Azure AD Authentication

In order to interact with the Azure Maps service, you'll need to create an instance of the MapsSearchClient class. The Azure Identity library makes it easy to add Azure Active Directory support for authenticating Azure SDK clients with their corresponding Azure services.

To use AAD authentication, set TENANT_ID, CLIENT_ID, and CLIENT_SECRET to environment variable and call DefaultAzureCredential() method to get credential. CLIENT_ID and CLIENT_SECRET are the service principal ID and secret that can access Azure Maps account.

We also need Azure Maps Client ID which can get from Azure Maps page > Authentication tab > "Client ID" in Azure Active Directory Authentication section.

// Create a MapsSearchClient that will authenticate through AAD
DefaultAzureCredential credential = new DefaultAzureCredential();
string clientId = "<My Map Account Client Id>";
MapsSearchClient client = new MapsSearchClient(credential, clientId);
Shared Access Signature (SAS) Authentication

Shared access signature (SAS) tokens are authentication tokens created using the JSON Web token (JWT) format and are cryptographically signed to prove authentication for an application to the Azure Maps REST API.

Before integrating SAS token authentication, we need to install Azure.ResourceManager and Azure.ResourceManager.Maps (version 1.1.0-beta.2 or higher):

dotnet add package Azure.ResourceManager
dotnet add package Azure.ResourceManager.Maps --prerelease

In the code, we need to import the following lines for both Azure Maps SDK and ResourceManager:

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

And then we can get SAS token via List Sas API and assign it to MapsSearchClient. In the follow code sample, we fetch a specific maps account resource, and create a SAS token for 1 day expiry time when the code is executed.

// Get your azure access token, for more details of how Azure SDK get your access token, please refer to
TokenCredential cred = new DefaultAzureCredential();
// Authenticate your client
ArmClient armClient = new ArmClient(cred);

string subscriptionId = "MyMapsSubscriptionId";
string resourceGroupName = "MyMapsResourceGroupName";
string accountName = "MyMapsAccountName";

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

// Assign SAS token information
// Every time you want to SAS token, update the principal ID, max rate, start and expiry time
string principalId = "MyManagedIdentityObjectId";
int maxRatePerSecond = 500;

// Set start and expiry time for the SAS token in round-trip date/time format
DateTime now = DateTime.Now;
string start = now.ToString("O");
string expiry = now.AddDays(1).ToString("O");

MapsAccountSasContent sasContent = new MapsAccountSasContent(MapsSigningKey.PrimaryKey, principalId, maxRatePerSecond, start, expiry);
Response<MapsAccountSasToken> sas = mapsAccount.GetSas(sasContent);

// Create a SearchClient that will authenticate via SAS token
AzureSasCredential sasCredential = new AzureSasCredential(sas.Value.AccountSasToken);
MapsSearchClient client = new MapsSearchClient(sasCredential);

Key concepts

MapsSearchClient is designed to:

  • Communicate with Azure Maps endpoint to query addresses or points of locations
  • Communicate with Azure Maps endpoint to request the geometry data such as a city or country outline for a set of entities
  • Communicate with Azure Maps endpoint to perform a free form search inside a single geometry or many of them

Thread safety

We guarantee that all client instance methods are thread-safe and independent of each other (guideline). This ensures that the recommendation of reusing client instances is always safe, even across threads.

You can familiarize yourself with different APIs using our samples.

Example Get Polygons

// Get Addresses
Response<SearchAddressResult> searchResult = await client.SearchAddressAsync("Seattle");

// Extract geometry ids from addresses
string geometry0Id = searchResult.Value.Results[0].DataSources.Geometry.Id;
string geometry1Id = searchResult.Value.Results[1].DataSources.Geometry.Id;

// Extract position coordinates
GeoPosition positionCoordinates = searchResult.Value.Results[0].Position;

// Get polygons from geometry ids
PolygonResult polygonResponse = await client.GetPolygonsAsync(new[] { geometry0Id, geometry1Id });

// Get polygons objects
IReadOnlyList<PolygonObject> polygonList = polygonResponse.Polygons;
Response<SearchAddressResult> fuzzySearchResponse = await client.FuzzySearchAsync("coffee", new FuzzySearchOptions
    Coordinates = new GeoPosition(121.56, 25.04),
    Language = SearchLanguage.EnglishUsa

// Print out the possible results
Console.WriteLine("The possible results for coffee shop:");
foreach (SearchAddressResultItem result in fuzzySearchResponse.Value.Results)
    Console.WriteLine("Coordinate: {0}, Address: {1}",
        result.Position, result.Address.FreeformAddress);

Example Reverse Search Cross Street Address

var reverseResult = await client.ReverseSearchCrossStreetAddressAsync(new ReverseSearchCrossStreetOptions
    Coordinates = new GeoPosition(121.0, 24.0),
    Language = SearchLanguage.EnglishUsa

Example Search Structured Address

var address = new StructuredAddress
    CountryCode = "US",
    StreetNumber = "15127",
    StreetName = "NE 24th Street",
    Municipality = "Redmond",
    CountrySubdivision = "WA",
    PostalCode = "98052"
Response<SearchAddressResult> searchResult = await client.SearchStructuredAddressAsync(address);

SearchAddressResultItem resultItem = searchResult.Value.Results[0];
Console.WriteLine("First result - Coordinate: {0}, Address: {1}",
    resultItem.Position, resultItem.Address.FreeformAddress);

Example Search Inside Geometry

GeoPolygon sfPolygon = new GeoPolygon(new[]
    new GeoPosition(-122.43576049804686, 37.752415234354402),
    new GeoPosition(-122.4330139160, 37.706604725423119),
    new GeoPosition(-122.36434936523438, 37.712059855877314),
    new GeoPosition(-122.43576049804686, 37.7524152343544)

GeoPolygon taipeiPolygon = new GeoPolygon(new[]
    new GeoPosition(121.56, 25.04),
    new GeoPosition(121.565, 25.04),
    new GeoPosition(121.565, 25.045),
    new GeoPosition(121.56, 25.045),
    new GeoPosition(121.56, 25.04)

// Search coffee shop in Both polygons, return results in en-US
Response<SearchAddressResult> searchResponse = await client.SearchInsideGeometryAsync("coffee", new GeoCollection(new[] { sfPolygon, taipeiPolygon }), new SearchInsideGeometryOptions
    Language = SearchLanguage.EnglishUsa

// Get Taipei Cafe and San Francisco cafe and print first place
SearchAddressResultItem taipeiCafe = searchResponse.Value.Results.Where(addressItem => addressItem.SearchAddressResultType == "POI" && addressItem.Address.Municipality == "Taipei City").First();
SearchAddressResultItem sfCafe = searchResponse.Value.Results.Where(addressItem => addressItem.SearchAddressResultType == "POI" && addressItem.Address.Municipality == "San Francisco").First();

Console.WriteLine("Possible Coffee shop in the Polygons:");
Console.WriteLine("Coffee shop address in Taipei: {0}", taipeiCafe.Address.FreeformAddress);
Console.WriteLine("Coffee shop address in San Francisco: {0}", sfCafe.Address.FreeformAddress);

Example Search Address

Response<SearchAddressResult> searchResult = await client.SearchAddressAsync("Seattle");

SearchAddressResultItem resultItem = searchResult.Value.Results[0];
Console.WriteLine("First result - Coordinate: {0}, Address: {1}",
    resultItem.Position, resultItem.Address.FreeformAddress);



When you interact with the Azure Maps Services, errors returned by the Language service correspond to the same HTTP status codes returned for REST API requests.

For example, if you try to search with invalid coordinates, a error is returned, indicating "Bad Request".400
