ConnectAsync with CancellationToken hangs

[vbisbest]

On iOS, it appears that using a cancellationtoken locks up the app and just hangs when the socket is really waiting to timeout. Here is the code:

` socket = new TcpSocketClient();

            cts = new CancellationTokenSource();
            cts.CancelAfter(10000);
            
            task = socket.ConnectAsync(serverInfoState.Server.RealIP, serverInfoState.Server.RealPort, false, cts.Token);
           await task;`

Am I using the token incorrectly? Connecting to a server that I know is unavailable causes the behavior. In the above code, the app remains responsive for 10 seconds, the it locks up for about another 30 seconds and eventually throws the cancellation error.

Same on UWP it seems..

Any code after using ConnectAsync is not beeing called. It hangs and does not throw any error or warning for me.
