Aspire.Azure.Storage.Queues

Aspire.Azure.Storage.Queues library

Registers QueueServiceClient as a singleton in the DI container for connecting to Azure Queue Storage. Enables corresponding health check, logging and telemetry.

Getting started

Prerequisites

• Azure subscription - create one for free
• Azure Storage account - create a storage account

Install the package

Install the .NET Aspire Azure Storage Queues library with NuGet:

dotnet add package Aspire.Azure.Storage.Queues

Usage example

In the Program.cs file of your project, call the AddAzureQueueClient extension method to register a QueueServiceClient for use via the dependency injection container. The method takes a connection name parameter.

builder.AddAzureQueueClient("queue");

You can then retrieve the QueueServiceClient instance using dependency injection. For example, to retrieve the client from a Web API controller:

private readonly QueueServiceClient _client;

public ProductsController(QueueServiceClient client)
{
    _client = client;
}

See the Azure.Storage.Queues documentation for examples on using the QueueServiceClient.

Configuration

The .NET Aspire Azure Storage Queues library provides multiple options to configure the Azure Storage Queues connection based on the requirements and conventions of your project. Note that either a ServiceUri or a ConnectionString is a required to be supplied.

Use a connection string

When using a connection string from the ConnectionStrings configuration section, you can provide the name of the connection string when calling builder.AddAzureQueueClient():

builder.AddAzureQueueClient("queueConnectionName");

And then the connection string will be retrieved from the ConnectionStrings configuration section. Two connection formats are supported:

Service URI

The recommended approach is to use a ServiceUri, which works with the AzureStorageQueuesSettings.Credential property to establish a connection. If no credential is configured, the DefaultAzureCredential is used.

{
  "ConnectionStrings": {
    "queueConnectionName": "https://{account_name}.queue.core.windows.net/"
  }
}

Connection string

Alternatively, an Azure Storage connection string can be used.

{
  "ConnectionStrings": {
    "queueConnectionName": "AccountName=myaccount;AccountKey=myaccountkey"
  }
}

Use configuration providers

The .NET Aspire Azure Storage Queues library supports Microsoft.Extensions.Configuration. It loads the AzureStorageQueuesSettings and QueueClientOptions from configuration by using the Aspire:Azure:Storage:Queues key. Example appsettings.json that configures some of the options:

{
  "Aspire": {
    "Azure": {
      "Storage": {
        "Queues": {
          "DisableHealthChecks": true,
          "DisableTracing": false,
          "ClientOptions": {
            "Diagnostics": {
              "ApplicationId": "myapp"
            }
          }
        }
      }
    }
  }
}

Use inline delegates

You can also pass the Action<AzureStorageQueuesSettings> configureSettings delegate to set up some or all the options inline, for example to disable health checks from code:

builder.AddAzureQueueClient("queue", settings => settings.DisableHealthChecks = true);

You can also setup the QueueClientOptions using the optional Action<IAzureClientBuilder<QueueServiceClient, QueueClientOptions>> configureClientBuilder parameter of the AddAzureQueueClient method. For example, to set the first part of "User-Agent" headers for all requests issues by this client:

builder.AddAzureQueueClient("queue", configureClientBuilder: clientBuilder => clientBuilder.ConfigureOptions(options => options.Diagnostics.ApplicationId = "myapp"));

AppHost extensions

In your AppHost project, install the Aspire Azure Storage Hosting library with NuGet:

dotnet add package Aspire.Hosting.Azure.Storage

Then, in the Program.cs file of AppHost, add a Storage Queue connection and consume the connection using the following methods:

var queue = builder.ExecutionContext.IsPublishMode
    ? builder.AddAzureStorage("storage").AddQueues("queue")
    ? builder.AddConnectionString("queue");

var myService = builder.AddProject<Projects.MyService>()
                       .WithReference(queue);

The AddQueues method adds an Azure Storage queue to the builder. Or AddConnectionString can be used to read connection information from the AppHost's configuration (for example, from "user secrets") under the ConnectionStrings:queue config key. The WithReference method passes that connection information into a connection string named queue in the MyService project. In the Program.cs file of MyService, the connection can be consumed using:

builder.AddAzureQueueClient("queue");
