Description xambugz 2015-04-13 09:28:32 UTC
It is normal and common to use Stream objects in using() blocks. So this is quite undesirable. SslStream.Dispose() hangs indefinitely. Problem does not exist in .Net.

using System.Net;
using System.Net.Sockets;
using System.Net.Security;

const string hostname = "example.com";  // Name of some arbitrary https server
const int port = 443;
IPAddress[] ipAddresses = Dns.GetHostAddresses(hostname);
foreach (var address in ipAddresses) {

    if (address.AddressFamily == AddressFamily.InterNetwork || address.AddressFamily == AddressFamily.InterNetworkV6) {
        TcpClient client = new TcpClient(address.AddressFamily);
        client.Connect(address, port);

        using (var mySslStream = new SslStream(client.GetStream(), leaveInnerStreamOpen: false)) {
            try {
            catch (Exception e) {
        }  // FAILS HERE
