FoundationDB — Running a cluster & connecting from .NET (Aspire, the native client)

The foundationdb-keys-and-layers, foundationdb-transactions, and foundationdb-advanced-layers skills all start from an IFdbDatabase / IFdbDatabaseProvider you already have. This skill is about getting there: standing up a cluster, loading the native client correctly, and connecting — including the .NET Aspire integration shipped in this repo (FoundationDB.Aspire.Hosting + FoundationDB.Aspire).

1. Getting an `IFdbDatabaseProvider`

Application code resolves an IFdbDatabaseProvider (then await provider.GetDatabase(ct) or, more commonly, the retry-loop methods). Three ways to create one:

Way	API	When
Plain DI	`services.AddFoundationDb(apiVersion, opt => …)` → `IFdbDatabaseProviderBuilder` (registers `IFdbDatabaseProvider`)	a regular host, you supply the cluster file via config
No DI	`FdbDatabaseProvider.Create(new FdbDatabaseProviderOptions { ApiVersion = 730, … })`	tools/tests/standalone; call `provider.Start()`
Aspire client	`builder.AddFoundationDb("fdb", settings, options)`	the connection string is injected by an Aspire AppHost (see §3)

apiVersion selects the client API level and caps the features you can use: 730 ⇒ FoundationDB 7.3 semantics, 740 ⇒ 7.4. This client accepts 610 to 740, and Fdb.DefaultApiVersion is 730, which is why 730 appears in most examples. Pick the level whose semantics you actually rely on, not the newest available: raising it is a behavior change, and it must stay ≤ what the cluster supports. The provider also carries a root FdbPath (a directory-layer partition); everything else resolves relative to it.

Plain-DI / no-DI namespaces: FoundationDB.DependencyInjection. These all still need the native client loaded (§5).

2. The Aspire AppHost integration (`FoundationDB.Aspire.Hosting`)

On a IDistributedApplicationBuilder (the AppHost), namespace Aspire.Hosting:

// starts a FoundationDB cluster as a Docker container, and emits a connection string named "fdb"
var fdb = builder.AddFoundationDb("fdb",
        apiVersion: 730,
        root: "/MyApp")                            // clusterVersion omitted on purpose - see below
    .WithLifetime(ContainerLifetime.Persistent);   // reuse the container across runs (faster restarts)

builder.AddProject<Projects.MyApp>("app")
    .WithReference(fdb)                            // injects the "fdb" connection string into the app
    .WaitFor(fdb);                                 // hold the app until the cluster is healthy

Prefer omitting clusterVersion. Left out, the hosting package picks its own last-known-good Docker tag for the major it selects (the FdbAspireHostingExtensions.LatestVersionNN constants, refreshed from Docker Hub by scripts/check-fdb-image-tags.ps1). A tag you hardcode is a number that rots in your AppHost: pin one only when you need a specific image, and then treat it as something to review, alongside rollForward: FdbVersionPolicy.Exact.
AddFoundationDb(...) → IResourceBuilder<FdbClusterResource> runs a container.
A fresh volume self-provisions. On first start the integration runs configure new single ssd inside the container (a brand-new cluster has no database until then), and WaitFor(fdb) holds dependents until the database answers. An already-configured database is left untouched. Opt out with .WithAutoProvisioning(false); run mode only.
AddFoundationDbCluster(name, apiVersion, root, clusterFile?, clusterVersion?) → IResourceBuilder<FdbConnectionResource> instead connects to an already-running cluster (no container) given a cluster file.
FdbVersionPolicy (Exact, etc.) lives in Aspire.Hosting.ApplicationModel. .WithDefaults(timeout, retryLimit, tracing) tunes the connection.

AppHost project setup: Sdk="Aspire.AppHost.Sdk/<ver>"; reference FoundationDB.Aspire.Hosting with IsAspireProjectResource="false" (it's a compile dependency for AddFoundationDb); reference each app project normally (those are launched as resources — their TFM need not match the AppHost).

3. The Aspire client integration (`FoundationDB.Aspire`)

In the app (not the AppHost), on an IHostApplicationBuilder, namespace Microsoft.Extensions.Hosting:

// reads the "fdb" connection string injected by WithReference(fdb) and registers IFdbDatabaseProvider
builder.AddFoundationDb("fdb",
    settings => { /* FdbClientSettings: tracing, health checks, … */ },
    options  => options.UseNativeClient());        // load libfdb_c (see §5)

The app references FoundationDB.Aspire. The injected connection string looks like ApiVersion=730;Root=/MyApp;ClusterFileContents=…;ClusterVersion=7.4.6 (the ClusterVersion is whatever tag the AppHost resolved, so do not read the one in this example as a recommendation). Standalone (no AppHost), provide the cluster file via configuration instead.

Don't confuse the two AddFoundationDbs: the AppHost one (IDistributedApplicationBuilder, starts the container) vs the client one (IHostApplicationBuilder, consumes the connection). They have different receivers, so they never collide.

4. Launching the AppHost

Preferred: the aspire CLI — it provisions the dashboard, OTLP, and ports for you:

dotnet tool install --global aspire.cli          # one-time
aspire run --apphost path/to/MyApp.AppHost.csproj
# headless / CI: aspire run --apphost … --detach --non-interactive --format Json
#   → returns { appHostPid, dashboardUrl (with login token), logFile }

Fallback: plain dotnet run (or IDE F5) on the AppHost. This requires a Properties/launchSettings.json providing the dashboard + OTLP endpoints, e.g.:

{ "profiles": { "http": { "commandName": "Project",
  "applicationUrl": "http://localhost:15200",
  "environmentVariables": {
    "DOTNET_DASHBOARD_OTLP_ENDPOINT_URL": "http://localhost:19200",
    "DOTNET_RESOURCE_SERVICE_ENDPOINT_URL": "http://localhost:20200",
    "ASPIRE_ALLOW_UNSECURED_TRANSPORT": "true" } } } }

Without it, a bare dotnet run on the AppHost crashes at startup: "Failed to configure dashboard resource because ASPNETCORE_URLS … was not set / … OTLP endpoint must be provided." The aspire CLI does not need this file.

5. The native client (`libfdb_c`) — `UseNativeClient()`

The .NET client talks to the cluster through the native libfdb_c library. options.UseNativeClient(allowSystemFallback: false) loads only the copy shipped by the FoundationDB.Client.Native package.

That package ships libfdb_c for linux-arm64, linux-x64, win-x64, osx-arm64, and (since the 7.4.6 native repackaging) osx-x64, so UseNativeClient(allowSystemFallback: false) loads the redistributed client on macOS too, with no system install. Use the system fallback only when your FoundationDB.Client.Native pin predates the macOS RID you need:

install a system libfdb_c.dylib (Homebrew foundationdb, or the official client package) of a matching version (§6) and matching CPU arch (an arm64 process cannot load an x64 dylib), and
call UseNativeClient(allowSystemFallback: true).

The loader searches the app's output directory and the standard dyld paths, not /usr/local/lib by bare name. To force a system copy, place (or copy) libfdb_c.dylib next to the built app. Symptom when no client loads: DllNotFoundException: Unable to load shared library 'fdb_c'.

6. Client ⇄ cluster version compatibility (the silent hang)

The client library version must be compatible with the cluster version. A 7.3 client cannot talk to a 7.4 cluster.

Symptom: transactions hang (no exception); fdbcli against the cluster reports "One or more processes … incompatible" and "database is unavailable", even though the cluster is internally healthy.
Fix: make the AppHost clusterVersion (the Docker image tag) match the libfdb_c available to the app. Check the client with fdbcli --version, the server with docker exec <container> fdbcli --version. If you did not pin a tag, the mismatch is almost always a system libfdb_c shadowing the redistributed one (see §5), not the container.
The apiVersion (e.g. 730) must be ≤ the cluster's supported level; 730 ⇒ 7.3, 740 ⇒ 7.4.

For talking to multiple cluster versions from one process, FoundationDB's multi-version client loads several external libfdb_c libraries — but the simplest demo/dev setup is: one cluster version, one matching client library.

7. Golden rules & gotchas

✅ DO

Pick the provider source by context: Aspire client integration under an AppHost; plain services.AddFoundationDb(...) / FdbDatabaseProvider.Create(...) otherwise.
Launch the AppHost with aspire run; keep a launchSettings.json only as the dotnet run/F5 fallback.
Keep the cluster image and the client library on the same major.minor (7.4 with 7.4). Omitting clusterVersion lets the hosting package pair them for you against the libfdb_c that FoundationDB.Client.Native redistributes; pin it only when you supply your own client library, and then verify both with fdbcli --version.
On macOS, the redistributed client covers osx-arm64 and osx-x64 (since 7.4.6), so UseNativeClient(allowSystemFallback: false) works; fall back to a system libfdb_c.dylib and allowSystemFallback: true only for an older pin without your RID.

⚠️ GOTCHAS

Transactions that hang on a brand-new cluster are almost always a client/cluster version mismatch, not a deadlock — check versions first.
DllNotFoundException: fdb_c ⇒ no native client found; on macOS the package ships none (see §5).
AppHost dotnet run crash about ASPNETCORE_URLS / OTLP ⇒ missing launchSettings.json, or just use aspire run.
AddFoundationDb "ambiguous" / wrong overload ⇒ you imported the wrong namespace; the AppHost call is on IDistributedApplicationBuilder (Aspire.Hosting), the client call on IHostApplicationBuilder (Microsoft.Extensions.Hosting).
WithLifetime(ContainerLifetime.Persistent) keeps the cluster's data across runs — handy in dev, but remember to docker rm -f it when you want a clean slate.

# FoundationDB — Running a cluster & connecting from .NET (Aspire, the native client)

The **`foundationdb-keys-and-layers`**, **`foundationdb-transactions`**, and **`foundationdb-advanced-layers`** skills all start from an `IFdbDatabase` / `IFdbDatabaseProvider` you already have. This skill is about getting there: standing up a cluster, loading the native client correctly, and connecting — including the .NET Aspire integration shipped in this repo (`FoundationDB.Aspire.Hosting` + `FoundationDB.Aspire`).

---

## 1. Getting an `IFdbDatabaseProvider`

Application code resolves an **`IFdbDatabaseProvider`** (then `await provider.GetDatabase(ct)` or, more commonly, the retry-loop methods). Three ways to create one:

| Way | API | When |
|---|---|---|
| **Plain DI** | `services.AddFoundationDb(apiVersion, opt => …)` → `IFdbDatabaseProviderBuilder` (registers `IFdbDatabaseProvider`) | a regular host, you supply the cluster file via config |
| **No DI** | `FdbDatabaseProvider.Create(new FdbDatabaseProviderOptions { ApiVersion = 730, … })` | tools/tests/standalone; call `provider.Start()` |
| **Aspire client** | `builder.AddFoundationDb("fdb", settings, options)` | the connection string is injected by an Aspire AppHost (see §3) |

`apiVersion` selects the client API level and **caps the features you can use**: `730` ⇒ FoundationDB 7.3 semantics, `740` ⇒ 7.4. This client accepts **610 to 740**, and `Fdb.DefaultApiVersion` is **730**, which is why 730 appears in most examples. Pick the level whose semantics you actually rely on, not the newest available: raising it is a behavior change, and it must stay ≤ what the cluster supports. The provider also carries a **root** `FdbPath` (a directory-layer partition); everything else resolves relative to it.

Plain-DI / no-DI namespaces: `FoundationDB.DependencyInjection`. These all still need the **native client** loaded (§5).

---

## 2. The Aspire AppHost integration (`FoundationDB.Aspire.Hosting`)

On a `IDistributedApplicationBuilder` (the AppHost), namespace `Aspire.Hosting`:

```csharp
// starts a FoundationDB cluster as a Docker container, and emits a connection string named "fdb"
var fdb = builder.AddFoundationDb("fdb",
        apiVersion: 730,
        root: "/MyApp")                            // clusterVersion omitted on purpose - see below
    .WithLifetime(ContainerLifetime.Persistent);   // reuse the container across runs (faster restarts)

builder.AddProject<Projects.MyApp>("app")
    .WithReference(fdb)                            // injects the "fdb" connection string into the app
    .WaitFor(fdb);                                 // hold the app until the cluster is healthy
```

- **Prefer omitting `clusterVersion`.** Left out, the hosting package picks its own last-known-good Docker tag for the major it selects (the `FdbAspireHostingExtensions.LatestVersionNN` constants, refreshed from Docker Hub by `scripts/check-fdb-image-tags.ps1`). A tag you hardcode is a number that rots in your AppHost: pin one only when you need a specific image, and then treat it as something to review, alongside `rollForward: FdbVersionPolicy.Exact`.
- `AddFoundationDb(...)` → `IResourceBuilder<FdbClusterResource>` **runs a container**.
- **A fresh volume self-provisions.** On first start the integration runs `configure new single ssd` inside the container (a brand-new cluster has no database until then), and `WaitFor(fdb)` holds dependents until the database answers. An already-configured database is left untouched. Opt out with `.WithAutoProvisioning(false)`; run mode only.
- `AddFoundationDbCluster(name, apiVersion, root, clusterFile?, clusterVersion?)` → `IResourceBuilder<FdbConnectionResource>` instead **connects to an already-running cluster** (no container) given a cluster file.
- `FdbVersionPolicy` (`Exact`, etc.) lives in `Aspire.Hosting.ApplicationModel`. `.WithDefaults(timeout, retryLimit, tracing)` tunes the connection.

**AppHost project setup:** `Sdk="Aspire.AppHost.Sdk/<ver>"`; reference `FoundationDB.Aspire.Hosting` with `IsAspireProjectResource="false"` (it's a *compile* dependency for `AddFoundationDb`); reference each app project normally (those are launched as resources — their TFM need not match the AppHost).

---

## 3. The Aspire client integration (`FoundationDB.Aspire`)

In the **app** (not the AppHost), on an `IHostApplicationBuilder`, namespace `Microsoft.Extensions.Hosting`:

```csharp
// reads the "fdb" connection string injected by WithReference(fdb) and registers IFdbDatabaseProvider
builder.AddFoundationDb("fdb",
    settings => { /* FdbClientSettings: tracing, health checks, … */ },
    options  => options.UseNativeClient());        // load libfdb_c (see §5)
```

The app references `FoundationDB.Aspire`. The injected connection string looks like `ApiVersion=730;Root=/MyApp;ClusterFileContents=…;ClusterVersion=7.4.6` (the `ClusterVersion` is whatever tag the AppHost resolved, so do not read the one in this example as a recommendation). Standalone (no AppHost), provide the cluster file via configuration instead.

> Don't confuse the two `AddFoundationDb`s: the **AppHost** one (`IDistributedApplicationBuilder`, starts the container) vs the **client** one (`IHostApplicationBuilder`, consumes the connection). They have different receivers, so they never collide.

---

## 4. Launching the AppHost

**Preferred: the `aspire` CLI** — it provisions the dashboard, OTLP, and ports for you:

```bash
dotnet tool install --global aspire.cli          # one-time
aspire run --apphost path/to/MyApp.AppHost.csproj
# headless / CI: aspire run --apphost … --detach --non-interactive --format Json
#   → returns { appHostPid, dashboardUrl (with login token), logFile }
```

**Fallback: plain `dotnet run`** (or IDE F5) on the AppHost. This requires a **`Properties/launchSettings.json`** providing the dashboard + OTLP endpoints, e.g.:

```json
{ "profiles": { "http": { "commandName": "Project",
  "applicationUrl": "http://localhost:15200",
  "environmentVariables": {
    "DOTNET_DASHBOARD_OTLP_ENDPOINT_URL": "http://localhost:19200",
    "DOTNET_RESOURCE_SERVICE_ENDPOINT_URL": "http://localhost:20200",
    "ASPIRE_ALLOW_UNSECURED_TRANSPORT": "true" } } } }
```

Without it, a bare `dotnet run` on the AppHost crashes at startup: *"Failed to configure dashboard resource because ASPNETCORE_URLS … was not set / … OTLP endpoint must be provided."* The `aspire` CLI does not need this file.

---

## 5. The native client (`libfdb_c`) — `UseNativeClient()`

The .NET client talks to the cluster through the native **`libfdb_c`** library. `options.UseNativeClient(allowSystemFallback: false)` loads **only** the copy shipped by the `FoundationDB.Client.Native` package.

That package ships `libfdb_c` for `linux-arm64`, `linux-x64`, `win-x64`, `osx-arm64`, and (since the 7.4.6 native repackaging) `osx-x64`, so `UseNativeClient(allowSystemFallback: false)` loads the redistributed client on macOS too, with no system install. Use the system fallback only when your `FoundationDB.Client.Native` pin predates the macOS RID you need:

1. install a system `libfdb_c.dylib` (Homebrew `foundationdb`, or the official client package) of a matching version (§6) and matching CPU arch (an arm64 process cannot load an x64 dylib), and
2. call `UseNativeClient(allowSystemFallback: true)`.

The loader searches the **app's output directory** and the standard dyld paths, not `/usr/local/lib` by bare name. To force a system copy, place (or copy) `libfdb_c.dylib` next to the built app. Symptom when no client loads: `DllNotFoundException: Unable to load shared library 'fdb_c'`.

---

## 6. Client ⇄ cluster version compatibility (the silent hang)

The **client library version must be compatible with the cluster version.** A 7.3 client **cannot** talk to a 7.4 cluster.

- Symptom: transactions **hang** (no exception); `fdbcli` against the cluster reports *"One or more processes … incompatible"* and *"database is unavailable"*, even though the cluster is internally healthy.
- Fix: make the AppHost `clusterVersion` (the Docker image tag) match the `libfdb_c` available to the app. Check the client with `fdbcli --version`, the server with `docker exec <container> fdbcli --version`. If you did not pin a tag, the mismatch is almost always a **system** `libfdb_c` shadowing the redistributed one (see §5), not the container.
- The `apiVersion` (e.g. `730`) must be ≤ the cluster's supported level; `730` ⇒ 7.3, `740` ⇒ 7.4.

For talking to **multiple** cluster versions from one process, FoundationDB's multi-version client loads several external `libfdb_c` libraries — but the simplest demo/dev setup is: one cluster version, one matching client library.

## 7. Golden rules & gotchas

✅ **DO**
- Pick the provider source by context: Aspire client integration under an AppHost; plain `services.AddFoundationDb(...)` / `FdbDatabaseProvider.Create(...)` otherwise.
- Launch the AppHost with `aspire run`; keep a `launchSettings.json` only as the `dotnet run`/F5 fallback.
- Keep the cluster image and the client library on the **same major.minor** (7.4 with 7.4). Omitting `clusterVersion` lets the hosting package pair them for you against the `libfdb_c` that `FoundationDB.Client.Native` redistributes; pin it only when you supply your own client library, and then verify both with `fdbcli --version`.
