You are an expert in Shiny's .NET Aspire integrations:

1. Shiny.Aspire.Orleans — Zero-friction integration between .NET Aspire and Microsoft Orleans for ADO.NET storage backends. Automatically provisions Orleans database schemas and wires up clustering, grain persistence, and reminders from Aspire configuration.
2. Shiny.Aspire.Hosting.Gluetun — Aspire hosting integration for Gluetun VPN containers. Models Gluetun as a first-class Aspire resource and lets other containers route their traffic through the VPN tunnel.

When to Use This Skill

Invoke this skill when the user wants to:

• Set up Orleans with .NET Aspire using ADO.NET storage (PostgreSQL, SQL Server, or MySQL)
• Automatically create Orleans database schemas from Aspire
• Configure an Orleans silo with ADO.NET providers from Aspire-injected config
• Configure an Orleans client with ADO.NET clustering from Aspire-injected config
• Use WithDatabaseSetup to auto-provision Orleans tables
• Use silo.UseAdoNet() to configure a silo inside UseOrleans
• Use client.UseAdoNetClient() to configure a client inside UseOrleansClient
• Select which Orleans features to provision (clustering, persistence, reminders)
• Set up multiple named grain storage providers
• Add a Gluetun VPN container to an Aspire app
• Route container traffic through a VPN tunnel
• Configure VPN providers, WireGuard, or OpenVPN in Aspire
• Use AddGluetun, WithRoutedContainer, WithVpnProvider, WithWireGuard, or WithOpenVpn
• Set up Docker Compose publishing with VPN network mode and port transfer

Architecture: Provider Registration

The Server and Client packages register Orleans provider builders via [assembly: RegisterProvider] attributes. When Orleans calls ApplyConfiguration during UseOrleans(), it reads the Aspire-injected configuration (e.g. Orleans:Clustering:ProviderType = "PostgresDatabase") and resolves the matching provider builder automatically. The provider builder maps the database type to the correct ADO.NET invariant and resolves the connection string from the ServiceKey.

This means:

• No manual configuration — providers are resolved automatically from Aspire config.
• Extension methods — UseAdoNet() on ISiloBuilder and UseAdoNetClient() on IClientBuilder are identity methods for discoverability. The actual wiring happens through the registered provider builders.
• Composable — because configuration happens inside UseOrleans(silo => { ... }) or UseOrleansClient(client => { ... }), users can add other features alongside.

Setup

1. Aspire AppHost

Install Shiny.Aspire.Orleans.Hosting in the AppHost project.

using Shiny.Aspire.Orleans.Hosting;

var builder = DistributedApplication.CreateBuilder(args);

var db = builder.AddPostgres("pg")
    .WithPgAdmin()
    .AddDatabase("orleans-db");

var orleans = builder.AddOrleans("cluster")
    .WithClustering(db)
    .WithGrainStorage("Default", db)
    .WithReminders(db)
    .WithDatabaseSetup(db); // creates all Orleans tables automatically

builder.AddProject<Projects.MySilo>("silo")
    .WithReference(orleans)
    .WaitFor(db);

builder.AddProject<Projects.MyApi>("api")
    .WithReference(orleans.AsClient())
    .WaitFor(db);

builder.Build().Run();

2. Orleans Silo

Install Shiny.Aspire.Orleans.Server in the silo project. Call silo.UseAdoNet() inside UseOrleans.

using Shiny.Aspire.Orleans.Server;

var builder = WebApplication.CreateBuilder(args);

builder.UseOrleans(silo =>
{
    silo.UseAdoNet();
});

var app = builder.Build();
app.Run();

3. Orleans Client

Install Shiny.Aspire.Orleans.Client in the client project (e.g. an API gateway). Call client.UseAdoNetClient() inside UseOrleansClient.

using Shiny.Aspire.Orleans.Client;

var builder = WebApplication.CreateBuilder(args);

builder.UseOrleansClient(client =>
{
    client.UseAdoNetClient();
});

var app = builder.Build();

app.MapGet("/counter/{name}", async (string name, IClusterClient client) =>
{
    var grain = client.GetGrain<ICounterGrain>(name);
    var count = await grain.GetCount();
    return Results.Ok(new { name, count });
});

app.Run();

API Reference

Hosting Package — Shiny.Aspire.Orleans.Hosting

WithDatabaseSetup

public static OrleansService WithDatabaseSetup(
    this OrleansService orleans,
    IResourceBuilder<IResourceWithConnectionString> database,
    OrleansFeature features = OrleansFeature.All
)

Subscribes to Aspire's ResourceReadyEvent for the database resource. When the database is up and accepting connections, it executes embedded Orleans SQL schema scripts. The database type (PostgreSQL, SQL Server, MySQL) is auto-detected from the Aspire resource.

Parameters:

• orleans — The Orleans service from builder.AddOrleans()
• database — An Aspire database resource (e.g. from AddPostgres, AddSqlServer, AddMySql)
• features — Which Orleans features to provision (default: OrleansFeature.All)

OrleansFeature (Flags Enum)

[Flags]
public enum OrleansFeature
{
    Clustering = 1,   // Membership tables for silo discovery
    Persistence = 2,  // Grain storage tables
    Reminders = 4,    // Reminder tables
    All = Clustering | Persistence | Reminders
}

Use to limit which schemas are provisioned:

// Only clustering and persistence (no reminders)
orleans.WithDatabaseSetup(db, OrleansFeature.Clustering | OrleansFeature.Persistence);

// Only clustering
orleans.WithDatabaseSetup(db, OrleansFeature.Clustering);

DatabaseType (Enum)

public enum DatabaseType
{
    SqlServer,
    PostgreSQL,
    MySql
}

Auto-detected from the Aspire resource — you do not need to specify this directly.

Server Package — Shiny.Aspire.Orleans.Server

UseAdoNet (ISiloBuilder extension)

public static ISiloBuilder UseAdoNet(this ISiloBuilder siloBuilder)

Marker extension for discoverability. The actual provider registration happens automatically via [assembly: RegisterProvider] attributes when the package is referenced. Providers are registered for all three database types across Clustering, GrainStorage, and Reminders.

Call inside UseOrleans:

builder.UseOrleans(silo =>
{
    silo.UseAdoNet();
    // compose with other silo features here
});

Client Package — Shiny.Aspire.Orleans.Client

UseAdoNetClient (IClientBuilder extension)

public static IClientBuilder UseAdoNetClient(this IClientBuilder clientBuilder)

Marker extension for discoverability. Registers ADO.NET clustering provider builders for both Silo and Client targets. Clients do not need grain storage or reminders.

Call inside UseOrleansClient:

builder.UseOrleansClient(client =>
{
    client.UseAdoNetClient();
});

Configuration Flow

Aspire injects the following configuration when you use .WithReference(orleans):

Orleans:Clustering:ProviderType = "PostgresDatabase"
Orleans:Clustering:ServiceKey   = "orleans-db"
Orleans:GrainStorage:Default:ProviderType = "PostgresDatabase"
Orleans:GrainStorage:Default:ServiceKey   = "orleans-db"
Orleans:Reminders:ProviderType  = "PostgresDatabase"
Orleans:Reminders:ServiceKey    = "orleans-db"
ConnectionStrings:orleans-db    = "Host=...;Database=..."

Orleans' ApplyConfiguration reads these sections and delegates to the registered provider builders, which configure the ADO.NET providers with the correct connection strings and invariants.

Schema Provisioning Order

WithDatabaseSetup runs embedded SQL scripts in order:

1. Main — creates the OrleansQuery table (query registry)
2. Clustering — creates OrleansMembershipVersionTable, OrleansMembershipTable, and stored procedures
3. Persistence — creates OrleansStorage table and stored procedures
4. Reminders — creates OrleansRemindersTable and stored procedures

Switching Databases

Swap the Aspire resource builder — everything else stays the same:

// PostgreSQL
var db = builder.AddPostgres("pg").AddDatabase("orleans-db");

// SQL Server
var db = builder.AddSqlServer("sql").AddDatabase("orleans-db");

// MySQL
var db = builder.AddMySql("mysql").AddDatabase("orleans-db");

Multiple Grain Storage Providers

// AppHost
var orleans = builder.AddOrleans("cluster")
    .WithClustering(db)
    .WithGrainStorage("Default", db)
    .WithGrainStorage("Archive", archiveDb)
    .WithDatabaseSetup(db);

// Grain
public class MyGrain(
    [PersistentState("state", "Default")] IPersistentState<MyState> state,
    [PersistentState("archive", "Archive")] IPersistentState<ArchiveState> archive
) : Grain, IMyGrain { }

Each named provider reads from Orleans:GrainStorage:{Name}:ProviderType and Orleans:GrainStorage:{Name}:ServiceKey.

Code Generation Best Practices

1. Always use WithDatabaseSetup in the AppHost to auto-provision schemas — never require manual SQL scripts.
2. Always call WaitFor(db) on projects that reference Orleans, so the database is ready before the silo starts.
3. Use .AsClient() when wiring a client project — this provides only clustering config, not full silo config.
4. Use UseOrleans and UseOrleansClient — call silo.UseAdoNet() in silo projects inside UseOrleans and client.UseAdoNetClient() in client projects inside UseOrleansClient.
5. Feature flags are optional — only use OrleansFeature flags if the user explicitly wants to skip certain schemas.
6. Don't hardcode connection strings — Aspire injects them automatically via configuration.
7. Don't manually configure ADO.NET invariants — the packages auto-detect the correct invariant from the provider type.
8. Use named grain storage for multiple persistence stores — each name maps to a separate configuration section.

Gluetun VPN — Shiny.Aspire.Hosting.Gluetun

Setup

Install Shiny.Aspire.Hosting.Gluetun in the Aspire AppHost project.

var builder = DistributedApplication.CreateBuilder(args);

var vpn = builder.AddGluetun("vpn")
    .WithVpnProvider("mullvad")
    .WithWireGuard(builder.AddParameter("wireguard-key", secret: true))
    .WithServerCountries("US", "Canada");

var scraper = builder.AddContainer("scraper", "my-scraper")
    .WithHttpEndpoint(targetPort: 8080);

vpn.WithRoutedContainer(scraper);

builder.Build().Run();

API Reference

AddGluetun

public static IResourceBuilder<GluetunResource> AddGluetun(
    this IDistributedApplicationBuilder builder,
    string name,
    int? httpProxyPort = null,
    int? shadowsocksPort = null)

Creates a Gluetun container resource with:

• Image: qmcgaw/gluetun:latest from docker.io
• --cap-add NET_ADMIN runtime arg
• --device /dev/net/tun runtime arg
• Docker Compose publish callback that sets cap_add, devices, and transfers ports from routed containers

Optional port parameters expose Gluetun's built-in HTTP proxy (target port 8888) and Shadowsocks proxy (target port 8388).

WithVpnProvider

vpn.WithVpnProvider("mullvad");

Sets the VPN_SERVICE_PROVIDER environment variable. Required for all Gluetun setups.

WithOpenVpn

// String credentials
vpn.WithOpenVpn("username", "password");

// Aspire parameter resources (recommended for secrets)
vpn.WithOpenVpn(
    builder.AddParameter("openvpn-user"),
    builder.AddParameter("openvpn-pass", secret: true));

Sets VPN_TYPE=openvpn, OPENVPN_USER, and OPENVPN_PASSWORD.

WithWireGuard

// String key
vpn.WithWireGuard("my-private-key");

// Aspire parameter resource (recommended for secrets)
vpn.WithWireGuard(builder.AddParameter("wireguard-key", secret: true));

Sets VPN_TYPE=wireguard and WIREGUARD_PRIVATE_KEY.

WithServerCountries / WithServerCities

vpn.WithServerCountries("US", "Canada", "Germany");
vpn.WithServerCities("New York", "Toronto");

Values are comma-joined and set as SERVER_COUNTRIES / SERVER_CITIES environment variables.

WithHttpProxy / WithShadowsocks

vpn.WithHttpProxy();           // HTTPPROXY=on
vpn.WithHttpProxy(false);      // HTTPPROXY=off
vpn.WithShadowsocks();         // SHADOWSOCKS=on
vpn.WithShadowsocks(false);    // SHADOWSOCKS=off

WithFirewallOutboundSubnets

vpn.WithFirewallOutboundSubnets("10.0.0.0/8", "192.168.0.0/16");

Sets FIREWALL_OUTBOUND_SUBNETS (comma-joined). Useful for allowing traffic to local network resources outside the VPN tunnel.

WithTimezone

vpn.WithTimezone("America/New_York");

Sets the TZ environment variable.

WithGluetunEnvironment

// String value
vpn.WithGluetunEnvironment("DNS_ADDRESS", "1.1.1.1");

// Aspire parameter resource
vpn.WithGluetunEnvironment("UPDATER_PERIOD", builder.AddParameter("updater-period"));

Generic passthrough for any Gluetun environment variable not covered by the typed methods.

WithRoutedContainer

vpn.WithRoutedContainer(scraper);
vpn.WithRoutedContainer(downloader);

Routes a container's traffic through the Gluetun VPN tunnel. Each call:

1. Adds a GluetunRoutedResourceAnnotation to the Gluetun resource
2. Sets --network container:<vpn-name> runtime args on the routed container
3. On Docker Compose publish, sets network_mode: "service:<vpn-name>" and transfers port mappings to the Gluetun service

You can route multiple containers through the same VPN.

Docker Compose Output

When published as Docker Compose, routed containers automatically get:

services:
  vpn:
    image: qmcgaw/gluetun:latest
    cap_add:
      - NET_ADMIN
    devices:
      - /dev/net/tun
    environment:
      - VPN_SERVICE_PROVIDER=mullvad
      - VPN_TYPE=wireguard
      - WIREGUARD_PRIVATE_KEY=${wireguard-key}
      - SERVER_COUNTRIES=US,Canada
    ports:
      - "8080:8080"    # forwarded from scraper
  scraper:
    image: my-scraper
    network_mode: "service:vpn"
    # ports moved to vpn service

Types

GluetunResource

namespace Aspire.Hosting.ApplicationModel;
public class GluetunResource(string name) : ContainerResource(name);

GluetunRoutedResourceAnnotation

namespace Aspire.Hosting.ApplicationModel;
public sealed record GluetunRoutedResourceAnnotation(
    GluetunResource GluetunResource,
    ContainerResource RoutedResource) : IResourceAnnotation;

Stored on the Gluetun resource. References each container that routes through it.

Gluetun Code Generation Best Practices

1. Always use WithVpnProvider — it is required for Gluetun to connect to any VPN service.
2. Use ParameterResource for secrets — never hardcode private keys or passwords in the AppHost. Use builder.AddParameter("key", secret: true).
3. Call WithRoutedContainer on the VPN builder — not on the container. The method is on IResourceBuilder<GluetunResource>.
4. Ports transfer automatically — when a container is routed through Gluetun, its endpoints are served on the Gluetun container in Docker Compose. Do not manually duplicate port mappings.
5. Use WithGluetunEnvironment for provider-specific settings — the typed methods cover common settings, but many providers have additional options documented in the Gluetun wiki.
6. Use WithFirewallOutboundSubnets for local network access — if routed containers need to reach local services (databases, APIs) outside the VPN, allow those subnets explicitly.
7. Multiple containers can share one VPN — call WithRoutedContainer multiple times on the same Gluetun resource.
