Get started with the Redis integration

Redis® is the world’s fastest data platform for caching, vector search, and NoSQL databases. The Aspire Redis integration enables you to connect to existing Redis instances, or create new instances from .NET with the docker.io/library/redis container image.

Note

This page covers the Redis integration. For Garnet and Valkey (Redis-compatible alternatives), see their respective pages.

In this introduction, you’ll see how to install and use the Aspire Redis integrations in a simple configuration. If you already have this knowledge, see Redis hosting integration for full reference details.

Note

To follow this guide, you must have created an Aspire solution to work with. To learn how to do that, see Build your first Aspire app.

Set up hosting integration

To begin, install the Aspire Redis hosting integration in your Aspire AppHost project:

Aspire CLI

Aspire CLI — Ajouter le package Aspire.Hosting.Redis

aspire add redis

La CLI Aspire est interactive ; choisissez le résultat approprié lorsque demandé :

Aspire CLI — Exemple de sortie

Select an integration to add:

> redis (Aspire.Hosting.Redis)
> Other results listed as selectable options...

Note

S'il n'y a qu'un seul résultat, il est sélectionné automatiquement. Vous devez quand même confirmer la version.

apphost.cs (C# file-based app)

C# — AppHost.cs

#:package Aspire.Hosting.Redis@*

PackageReference (*.csproj)

XML — Ajouter la référence de package Aspire.Hosting.Redis

<PackageReference Include="Aspire.Hosting.Redis" Version="*" />

Next, in the AppHost project, create instances of Redis resources and pass them to the consuming client projects:

C# — AppHost.cs

var builder = DistributedApplication.CreateBuilder(args);

var cache = builder.AddRedis("cache");

var myService = builder.AddProject<Projects.ExampleProject>()
                       .WithReference(cache);

builder.Build().Run();

When Aspire adds a container image to the AppHost, it creates a new Redis instance on your local machine.

Astuce

If you’d rather connect to an existing Redis instance, call AsExisting instead.

Set up client integration

To get started with the Aspire Redis client integration, install the package:

.NET CLI

.NET CLI — Add Aspire.StackExchange.Redis package

dotnet add package Aspire.StackExchange.Redis

Program.cs (C# file-based app)

Program.cs

#:package Aspire.StackExchange.Redis@*

PackageReference (*.csproj)

XML — Add Aspire.StackExchange.Redis package reference

<PackageReference Include="Aspire.StackExchange.Redis" Version="*" />

In the Program.cs file of your client-consuming project, call the AddRedisClient extension method to register an IConnectionMultiplexer for use via the dependency injection container:

builder.AddRedisClient(connectionName: "cache");

Astuce

The connectionName parameter must match the name used when adding the Redis resource in the AppHost project.

You can then retrieve the IConnectionMultiplexer instance using dependency injection:

public class ExampleService(IConnectionMultiplexer connectionMux)
{
    // Use connection multiplexer...
}
