Azure client library integration for ASP.NET Core

Microsoft.Extensions.Azure.Core provides shared primitives to integrate Azure clients with ASP.NET Core dependency injection and configuration systems.

Source code | Package (NuGet)

Getting started

Install the package

Install the ASP.NET Core integration library using NuGet:

dotnet add package Microsoft.Extensions.Azure

Register clients

Make a call to AddAzureClients in your app's ConfigureServices method. You can use the provided builder to register client instances with your dependency injection container.

public void ConfigureServices(IServiceCollection services)
    // Registering policy to use in ConfigureDefaults later

    services.AddAzureClients(builder => {
        // Register blob service client and initialize it using the KeyVault section of configuration
            // Set the name for this client registration
            // Set the credential for this client registration
            .WithCredential(new ClientSecretCredential("<tenant_id>", "<client_id>", "<client_secret>"))
            // Configure the client options
            .ConfigureOptions(options => options.Retry.MaxRetries = 10);

        // Adds a secret client using the provided endpoint and default credential set later
        builder.AddSecretClient(new Uri(""));

        // Configures environment credential to be used by default for all clients that require TokenCredential
        // and doesn't override it on per registration level
        builder.UseCredential(new EnvironmentCredential());

        // This would use configuration for auth and client settings

        // Configure global retry mode
        builder.ConfigureDefaults(options => options.Retry.Mode = RetryMode.Exponential);

        // Advanced configure global defaults
        builder.ConfigureDefaults((options, provider) =>  options.AddPolicy(provider.GetService<DependencyInjectionEnabledPolicy>(), HttpPipelinePosition.PerCall));

        // Register blob service client and initialize it using the Storage section of configuration

Inject clients

To use the client request the client type from any place that supports Dependency Injection (constructors, Configure calls, @inject razor definitions etc.)

public void Configure(IApplicationBuilder app, SecretClient secretClient, IAzureClientFactory<BlobServiceClient> blobClientFactory)

Create named instances

If client is registered as a named client inject IAzureClientFactory<T> and call CreateClient passing the name:

BlobServiceClient blobServiceClient = blobClientFactory.CreateClient("NamedBlobClient");

Configuration file used in the sample above:

  "Logging": {
    "LogLevel": {
      "Default": "Debug"
  "AllowedHosts": "*",
  "Default": {
    "ClientId": "<client_id>",
    "ClientSecret": "<client_secret>",
    "TenantId": "<tenant_id>",

    "TelemetryPolicy": {
      "ApplicationId": "AppId"
  "KeyVault": {
    "VaultUri": "<vault_uri>"
  "Storage": {
    "serviceUri": "<service_uri>",
    "credential": {
      "accountName": "<account_name>",
      "accountKey": "<account_key>"

Registering a custom client factory

If you want to take control over how the client instance is created or need to use other dependencies during the client construction use the AddClient<TClient, TOptions> method.

Here's and example of how to use IOptions<T> instance to construct the client:

public class MyApplicationOptions
    public Uri KeyVaultEndpoint { get; set; }

public void ConfigureServices(IServiceCollection services)
    // Configure a custom options instance
    services.Configure<MyApplicationOptions>(options => options.KeyVaultEndpoint = new Uri("http://localhost/"));

    services.AddAzureClients(builder =>
        // Register a client using MyApplicationOptions to get constructor parameters
        builder.AddClient<SecretClient, SecretClientOptions>((options, credential, provider) =>
            var appOptions = provider.GetService<IOptions<MyApplicationOptions>>();
            return new SecretClient(appOptions.Value.KeyVaultEndpoint, credential, options);
