Need help getting StreamSocket.upgradeToSslAsync working

Question

I'm trying to write some test code to confirm a few pieces of upgradeToSslAsync's behavior.  The finalized code wouldn't look like this but here is my test code:

var sock = new Windows.Networking.Sockets.StreamSocket();
sock.connectAsync(new Windows.Networking.HostName("10.116.32.101"), "443", Windows.Networking.Sockets.SocketProtectionLevel.plainSocket).then(
   function success() {
      sock.upgradeToSslAsync(Windows.Networking.Sockets.SocketProtectionLevel.ssl, new Windows.Networking.Sockets.HostName("broker.testdomain.int")).then(
         function success() {
            // Blah
         },
         function error(reason) {
            // Blah
         });
   },
   function error(reason) {
      // Blah
   });

When I run that code, the upgradeToSslAsync call immediately throws an exception saying "Object doesn't support this action".  Is that a notification from the socket that the server side does not support upgrade to SSL or is there a different issue in my code that I'm not noticing?

Hi Adam,

The debugger is your friend!  If you break on that function and inspect your variables, you will see "Windows.Networking.Sockets" does not have a member "HostName".  You want to change your code per the documentation to this:

  sock.upgradeToSslAsync(Windows.Networking.Sockets.SocketProtectionLevel.ssl,

newWindows.Networking.HostName("jsanders4")).then(
