Declares asynchronous methods for data access layers.
| Name | Description |
|---|---|
| AutoCreateOption | When implemented by a class, returns which operations are performed when a session is connected to storage. Inherited from IDataLayer. |
| Connection | When implemented by a class, returns the connection if it is provided by storage. Inherited from IDataLayer. |
| Name | Description |

| CreateCommand() | When implemented by a class, creates a command if storage allows commands to be created. Inherited from IDataLayer. |
| Dispose() | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. Inherited from IDisposable. |
| GetDataLayerWideData(Object) | This member supports the internal infrastructure and is not intended to be used directly from your code. Inherited from IDataLayer. |
| ModifyData(ModificationStatement[]) | When implemented, updates data in a data store using the specified modification statements. Inherited from IDataLayer. |
| ModifyDataAsync(CancellationToken, ModificationStatement[]) | Asynchronously updates data in a data store, according to specified modification statements. |
