```

**Purpose:** Periodically saves data of type T asynchronously at regular intervals.&#x20;

**Parameters:**&#x20;

* key: A string to define the file path.&#x20;
* data: The data to save periodically, constrained to reference types.&#x20;
* intervalSeconds: The time interval (in seconds) between each save operation.&#x20;
* cancellationToken: A token to cancel the auto-save loop.&#x20;

**Return Value:** An async Task.

```csharp
public void AutoSave()
{
    _dataPersistenceService.AutoSaveAsync("Key", _data, 3, _cancellationToken);
}
