Azure Communication Network Traversal enables high bandwidth, low latency connections between peers for real-time communication scenarios and data transfer scenarios by providing access to low-level STUN and TURN services.
Source code | Product documentation
Install the Azure Communication Network Traversal client library for .NET with NuGet:
dotnet add package Azure.Communication.NetworkTraversal --version 1.0.0-beta.1
You need an Azure subscription and a Communication Service Resource to use this package.
To create a new Communication Service, you can use the Azure Portal, the Azure PowerShell, or the .NET management client library.
The networking client can be authenticated using a connection string acquired from an Azure Communication Resources in the Azure Portal.
// Get a connection string to our Azure Communication resource.
var connectionString = "<connection_string>";
var client = new CommunicationRelayClient(connectionString);
Or alternatively using the endpoint and access key acquired from an Azure Communication Resources in the Azure Portal.
var endpoint = new Uri("https://my-resource.communication.azure.com");
var accessKey = "<access_key>";
var client = new CommunicationRelayClient(endpoint, new AzureKeyCredential(accessKey));
Clients also have the option to authenticate using a valid Active Directory token.
var endpoint = new Uri("https://my-resource.communication.azure.com");
TokenCredential tokenCredential = new DefaultAzureCredential();
var client = new CommunicationRelayClient(endpoint, tokenCredential);
CommunicationRelayClient
provides the functionalities to gain STUN/TURN server URLs and credentials for access.
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.

Response<CommunicationRelayConfiguration> turnTokenResponse = await client.GetRelayConfigurationAsync(user);
DateTimeOffset turnTokenExpiresOn = turnTokenResponse.Value.ExpiresOn;
IReadOnlyList<CommunicationTurnServer> turnServers = turnTokenResponse.Value.TurnServers;
Console.WriteLine($"Expires On: {turnTokenExpiresOn}");
foreach (CommunicationTurnServer turnServer in turnServers)
{
foreach (string url in turnServer.Urls)
{
Console.WriteLine($"TURN Url: {url}");
}
Console.WriteLine($"TURN Username: {turnServer.Username}");
Console.WriteLine($"TURN Credential: {turnServer.Credential}");
