# Integrations Catalog — Complete Reference

Aspire has **144+ integrations** across 13 categories, with **90+ NuGet packages**. Each integration typically provides two packages:

- **Hosting package** (`Aspire.Hosting.*`) — adds the resource to the AppHost
- **Client package** (`Aspire.*`) — configures the client SDK in your service with health checks, telemetry, and retries

---

## Integration pattern

```csharp
// === AppHost (hosting side) ===
var redis = builder.AddRedis("cache");  // Aspire.Hosting.Redis
var api = builder.AddProject<Projects.Api>("api")
    .WithReference(redis);

// === Service (client side) — in API's Program.cs ===
builder.AddRedisClient("cache");        // Aspire.Redis
// Automatically configures: connection string, health checks, OpenTelemetry, retries
```

## Custom integrations

### Custom hosting integration

```csharp
public static class MyServiceExtensions
{
    public static IResourceBuilder<ContainerResource> AddMyService(
        this IDistributedApplicationBuilder builder, string name)
    {
        return builder.AddContainer(name, "my-registry/my-service")
            .WithHttpEndpoint(targetPort: 8080, name: "http")
            .WithEnvironment("MODE", "production");
    }
}
```

### Custom client integration

```csharp
public static class MyServiceClientExtensions
{
    public static IHostApplicationBuilder AddMyServiceClient(
        this IHostApplicationBuilder builder, string connectionName)
    {
        // Register client with DI
        builder.Services.AddHttpClient<MyServiceClient>(client =>
        {
            var conn = builder.Configuration.GetConnectionString(connectionName);
            client.BaseAddress = new Uri(conn!);
        });

        // Add health check
        builder.Services.AddHealthChecks()
            .AddUrlGroup(new Uri($"{connectionName}/health"), name: connectionName);

        return builder;
    }
}
```

### Secure communication between integrations

```csharp
// Enable TLS between services
var api = builder.AddProject<Projects.Api>("api")
    .WithHttpsEndpoint()
    .WithReference(redis)
    .WithTransport("https");
```
