Socket.RemoteEndPoint exception in OnWsDisconnected

[Dmitriy147]

In my websocket chat server I try to use Socket.RemoteEndPoint to show the IP-adress of client, but ,unfortunately, in case "OnWsDisconnected" in attemp to show IP of disconnected client it is an exception like:
System.ObjectDisposedException: "Cannot access a disposed object.
ObjectDisposed_ObjectName_Name".

With showing client ID in this situation has no problems!
Is it any way to show IP of disconnected client without making array of all clients IP?

Fixed in 5.0.8 please try!

No effect on 5.0.8.. From Google Chrome connect by websocket throw chat/index.html - connect by websockets - than disconnect - exception appeared..
My code:
public override void OnWsDisconnected()
{
Logger.Log("Отключился: " + Socket.RemoteEndPoint, 0, true);
Logger.Log("ID: " + Id.ToString(), 1, ful_log);
}

It's the behavior of .net Socket it will dispose RemoteEndPoint property on Socket.Close() call. OnWsDisconnected() is called after the socket is closed.

What do you think of introducing OnWsDisconnecting() callback with valid connected socket in it?

[chronoxor]

The flow can be the following:

OnWsDisconnecting();
Socket.Close();
OnWsDisconnected();
Socket.Dispose();

would be nice!

In our logs we store this information in a following way:
