Get started with the Redis Distributed Caching integration

The Redis® distributed caching integration is used to register an IDistributedCache provider backed by a Redis server with the docker.io/library/redis container image.

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

Catatan

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 — Tambahkan paket Aspire.Hosting.Redis

aspire add redis

Aspire CLI interaktif; pilih hasil pencarian yang sesuai saat diminta:

Aspire CLI — Contoh keluaran

Select an integration to add:

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

Catatan

Jika hanya ada satu hasil, akan dipilih otomatis. Versinya tetap perlu dikonfirmasi.

apphost.cs (C# file-based app)

C# — AppHost.cs

#:package Aspire.Hosting.Redis@*

PackageReference (*.csproj)

XML — Tambahkan referensi paket 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.

Tips

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

Set up client integration

To get started with the Redis distributed caching integration, install the package:

.NET CLI

.NET CLI — Add Aspire.StackExchange.Redis.DistributedCaching package

dotnet add package Aspire.StackExchange.Redis.DistributedCaching

Program.cs (C# file-based app)

Program.cs

#:package Aspire.StackExchange.Redis.DistributedCaching@*

PackageReference (*.csproj)

XML — Add Aspire.StackExchange.Redis.DistributedCaching package reference

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

In the Program.cs file of your client-consuming project, call the AddRedisDistributedCache extension to register the required services for distributed caching:

builder.AddRedisDistributedCache(connectionName: "cache");

Tips

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

You can then retrieve the IDistributedCache instance using dependency injection:

public class ExampleService(IDistributedCache cache)
{
    // Use cache...
}
