```csharp
public bool TryGetGrainContext(GrainId grainId, out IGrainContext? grainContext)
```

Attempts to find the [IGrainContext](/orleans/docs/api/csharp/microsoft.orleans.core.abstractions/orleans.runtime.igraincontext/) for the grain with the specified `grainId` by searching all silos in the cluster.

### Parameters

- `grainId` (`GrainId`): The ID of the grain to find.
- `grainContext` (`IGrainContext?`): When this method returns, contains the grain context if found; otherwise, `null`.

### Returns

`true` if the grain was found in one of the silos; otherwise, `false`.

```csharp
public Task WaitForClusterManifestToStabilizeAsync(bool didKill = false)
```

Wait for active silos to observe cluster manifest updates for all active silos.

### Parameters

- `didKill` (`bool`): Whether recent membership changes were done by graceful Stop.

```csharp
public Task WaitForDeactivationAsync(GrainId grainId)
```

Gets a `System.Threading.Tasks.Task` that completes when the current activation of the specified grain finishes deactivating. If the grain is not currently activated, returns `System.Threading.Tasks.Task.CompletedTask`.

### Parameters

- `grainId` (`GrainId`): The ID of the grain to observe.

### Returns

A task that completes when the grain's current activation has deactivated.

### Examples

```csharp
var deactivated = cluster.WaitForDeactivationAsync(grain.GetGrainId());
            await grain.DoDeactivate();
            await deactivated;
```

```csharp
public Task WaitForDeactivationAsync(IAddressable grain)
```

Gets a `System.Threading.Tasks.Task` that completes when the current activation of the specified grain finishes deactivating. If the grain is not currently activated, returns `System.Threading.Tasks.Task.CompletedTask`.

### Parameters

- `grain` (`IAddressable`): The grain to observe.

### Returns

A task that completes when the grain's current activation has deactivated.

### Examples

```csharp
var deactivated = cluster.WaitForDeactivationAsync(grain.GetGrainId());
            await grain.DoDeactivate();
            await deactivated;

```csharp
public Task WaitForLivenessToStabilizeAsync(bool didKill = false)
```

Wait for the silo liveness sub-system to detect and act on any recent cluster membership changes.

### Parameters

- `didKill` (`bool`): Whether recent membership changes we done by graceful Stop.
