A task that represents the asynchronous dispose operation.
Remarks
The DisposeAsync method enables you to perform a resource-intensive dispose operation without blocking the main thread. This performance consideration is particularly important in desktop apps where a time-consuming stream operation can block the UI thread and make the app appear as if it's not working. The async methods are used in conjunction with the async and await keywords in Visual Basic and C#.
This method disposes the stream by writing any changes to the backing store and closing the stream to release resources.
Calling DisposeAsync allows the resources used by the CryptoStream to be reallocated for other purposes. For more information, see Cleaning Up Unmanaged Resources.
