Can't get members in lobby.

[WingsDevelopment]

I don't know when to start lobby, because lobby.members always returns 0 members.. And I don't get why? Can anyone help me with this?
public void CreateLobby(string LobbyName, string LobbyPassword, ulong[] Radiant, ulong[] Dire)
{

        if (dota.Lobby != null)
        {
            UpdateStatus(DotaClientStatus.Warning, "Lobby: Creating a lobby when already in one.");
        }


        CMsgPracticeLobbySetDetails details = new CMsgPracticeLobbySetDetails();
        details.game_name = LobbyName;
        details.pass_key = LobbyPassword;
        details.game_mode = (uint)DOTA_GameMode.DOTA_GAMEMODE_AP; // game mode
        details.allow_cheats = true; // chitz
        details.server_region = (uint)ERegionCode.USEast;
        details.dota_tv_delay = LobbyDotaTVDelay.LobbyDotaTV_300;
        details.game_version = DOTAGameVersion.GAME_VERSION_CURRENT;
        details.visibility = DOTALobbyVisibility.DOTALobbyVisibility_Public;

        dota.CreateLobby(LobbyPassword, details);

        // wait for lobby to be created
        while (dota.Lobby == null)
        {
            Thread.Sleep(10);
        }
        UpdateStatus(DotaClientStatus.Normal, "Lobby: Lobby Created.");
        UpdateStatus(DotaClientStatus.Normal, "Lobby: Lobby Name: " + LobbyName);

        Thread.Sleep(1000);
        foreach (var p in Radiant)
        {
            dota.InviteToLobby(p);
        }
        foreach (var p in Dire)

        {
            OnLobbyCreated(dota.Lobby.lobby_id);
        }

        UpdateStatus(DotaClientStatus.Normal, "Lobby: Waiting for players to connect....");

        List<DateTime> NotificationTimeouts = new List<DateTime>();
        NotificationTimeouts.Add(DateTime.Now.AddMinutes(1));
        NotificationTimeouts.Add(NotificationTimeouts.Last().AddMinutes(1));

                continue;

            }

            if (DateTime.Now > NotificationTimeouts[0])
            {
                dota.SendChannelMessage(dota.Lobby.lobby_id, "Players have " + NotificationTimeouts.Count.ToString() + " minute" + (NotificationTimeouts.Count == 1 ? "" : "s") + " to join the lobby.");
                NotificationTimeouts.RemoveAt(0);
            }
        }

I think I found the problem. CSODOTALobby -> 'members' should be named 'all_members' to be able to fetch json from dota2 api
CSODOTALobby ->
[ProtoMember(2, Name = "members", DataFormat = DataFormat.Default)]
public List members { get; }
But this class is locked for me... Can anyone help me with this please?

You likely need to update the Protobuf definitions, which define the network messages. The last update in this repo is from 2019, so any change Valve made after that aren't reflected in the last NuGet release.

I'm sorry, can you be more clear? How do I update Protobuf definitions? And what are Protobuf definitions? Can you send me some guide for that please?
