Downloaded files are locked

[Zinal001]

I'm trying to move finished torrents to another directory, but the folder/files are still locked after download has been completed.

I'm using this code:

public static async Task<String> DownloadTorrent(String torrentFile)
{
	try
	{
		var parser = new BencodeNET.Parsing.BencodeParser();
		BencodeNET.Torrents.Torrent torrent = parser.Parse<BencodeNET.Torrents.Torrent>(torrentFile);

		using (Leak.Client.Swarm.SwarmClient client = new Leak.Client.Swarm.SwarmClient())
		{
			Leak.Client.Notification notification = null;
			var hash = Leak.Common.FileHash.Parse(torrent.OriginalInfoHash);

			List<String> allTrackers = new List<string>();
			foreach (var tr in torrent.Trackers)
				allTrackers.AddRange(tr);

			var session = await client.ConnectAsync(hash, allTrackers.ToArray());

			session.Download(@"C:\Torrents\InProgress");

			do
			{
				notification = await session.NextAsync();
				if (notification is Leak.Client.Notifications.DataChangedNotification datNot)
				{
					Console.WriteLine($"Downloading ({Math.Round((((double)datNot.Completed / (double)torrent.NumberOfPieces) * 100), 2)}%)");
				}
			}
			while (notification.Type != Leak.Client.NotificationType.DataCompleted);
		}

		if (System.IO.Directory.Exists($"C:\\Torrents\\InProgress\\{torrent.OriginalInfoHash}"))
		{
			System.IO.Directory.Move($"C:\\Torrents\\InProgress\\{torrent.OriginalInfoHash}", $"C:\\Torrents\\Finished\\{torrent.OriginalInfoHash}");
		}

		return $"C:\\Torrents\\Finished\\{torrent.OriginalInfoHash}";
	}
	catch(Exception ex)
	{
		System.Diagnostics.Debug.WriteLine(ex);
	}

	return null;
}

I always get a System.IO.IOException when trying to move the directory from InProgress to Finished: Access to the path 'C:\\Torrents\\InProgress\\[[REDACTED HASH]]' is denied.

If I restart the application and add code to move it before it tries to download them it moves the directory successfully.

I'm guessing either the SwarmClient or SwarmSession isn't releasing their resources properly.

How do you successfully download a file? I always get stuck at notification = await session.NextAsync(); and get an exception

System.TypeInitializationException:“The type initializer for 'Leak.Meta.Store.HashExtensions' threw an exception.”

What do you think this might be for?
