```csharp
public ValueTask<MembershipTableTestHandle> CreateAdditionalHandleAsync(string clusterId, CancellationToken cancellationToken = default(CancellationToken))
```

Acquires another handle in one of this fixture's owned scopes. Initialization is explicit.

### Parameters

- `clusterId` (`string`)
- `cancellationToken` (`CancellationToken`)

## DisposeAsync {#disposeasync-4e3e51ad}

```csharp
public ValueTask DisposeAsync()
```

Waits up to 30 seconds for cleanup. Owners remain alive until their cleanup operations complete.

## InitializeAsync(CancellationToken) {#initializeasync-system-threading-cancellationtoken-61c7634d}

```csharp
public ValueTask InitializeAsync(CancellationToken cancellationToken = default(CancellationToken))
```

Constructs and initializes the three required handles. Partial failures clean up acquired resources.

### Parameters

- `cancellationToken` (`CancellationToken`)

## RunAsync(Func&lt;MembershipTableTestFixture, CancellationToken, Task&gt;, CancellationToken) {#runasync-system-func-orleans-clustering-testkit-membershiptabletestfixture-syste-5082e477}

```csharp
public Task RunAsync(Func<MembershipTableTestFixture, CancellationToken, Task> action, CancellationToken cancellationToken = default(CancellationToken))
```

Runs a complete isolated case and preserves its primary failure if teardown also fails.

### Parameters

- `action` (`Func<MembershipTableTestFixture, CancellationToken, Task>`)
- `cancellationToken` (`CancellationToken`)
