Aspire.Hosting.Azure.Redis

Aspire.Hosting.Azure.Redis library

Provides extension methods and resource definitions for a .NET Aspire AppHost to configure Azure Cache for Redis.

Getting started

Prerequisites

• Azure subscription - create one for free

Install the package

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

dotnet add package Aspire.Hosting.Azure.Redis

Configure Azure Provisioning for local development

Adding Azure resources to the .NET Aspire application model will automatically enable development-time provisioning for Azure resources so that you don't need to configure them manually. Provisioning requires a number of settings to be available via .NET configuration. Set these values in user secrets in order to allow resources to be configured automatically.

{
    "Azure": {
      "SubscriptionId": "<your subscription id>",
      "ResourceGroupPrefix": "<prefix for the resource group>",
      "Location": "<azure location>"
    }
}

NOTE: Developers must have Owner access to the target subscription so that role assignments can be configured for the provisioned resources.

Usage example

Then, in the AppHost.cs file of AppHost, register a Redis server and consume the connection using the following methods:

var redis = builder.AddAzureRedis("cache");

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

The WithReference method configures a connection in the MyService project named cache. By default, AddAzureRedis configures Microsoft Entra ID authentication. This requires changes to applications that need to connect to these resources. In the Program.cs file of MyService, the redis connection can be consumed using the client library Aspire.StackExchange.Redis and Microsoft.Azure.StackExchangeRedis:

var azureOptionsProvider = new AzureOptionsProvider();
var configurationOptions = ConfigurationOptions.Parse(builder.Configuration.GetConnectionString("cache") ?? throw new InvalidOperationException("Could not find a 'cache' connection string."));
if (configurationOptions.EndPoints.Any(azureOptionsProvider.IsMatch))
{
    await configurationOptions.ConfigureForAzureWithTokenCredentialAsync(new DefaultAzureCredential());
}

builder.AddRedisClient("cache", configureOptions: options =>
{
    options.Defaults = configurationOptions.Defaults;
});
