Subject: XMPP connection to FaceBook Chat
Hello people!
I wrote my first test application for Windows Phone 7.
Authentication on facebook works, and all works fine except connection to chat.

According to MatriX tutorial I wrote this:

    private void button1_Click(object sender, RoutedEventArgs e)
    {
      Client.OnBeforeSasl += xmppClient_OnBeforeSasl;
      /*breakpoint1 here*/Client.Open();
    }

    private void xmppClient_OnBeforeSasl(object sender, Matrix.Xmpp.Sasl.SaslEventArgs e)
    {
      /*breakpoint2 here*/e.Auto = false;
      e.SaslMechanism = Matrix.Xmpp.Sasl.SaslMechanism.X_FACEBOOK_PLATFORM;
      e.SaslProperties = new Matrix.Xmpp.Sasl.Processor.Facebook.FacebookProperties
      {
        ApiKey = "xxxxxxxxxxxxx",
        ApiSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        SessionKey = AccessToken
      };
    }

Then I add a breakpoints where I marked.
But my program does not hit breakpoint2 =(
What I've done wrong?

And the next question: how can I determine that a connection was successful?
Client.Open() has no return value =(

Are you using the Mango version of MatriX? You can only connect with the Mango version to Facebook. Because Facebook does not support Bosh, and all version before Mango support no sockets which are required for XMPP login to Facebook.

I think it is because I do not set server, or domain. Or are they automatically set after
e.SaslMechanism = Matrix.Xmpp.Sasl.SaslMechanism.X_FACEBOOK_PLATFORM; ?

of course you have to set the Xmpp domain chat.facebook.com before you open the connection.

I've tried for two different variants but nothing changed =(

    private void button1_Click(object sender, RoutedEventArgs e)
    {
      Client.OnBeforeSasl += xmppClient_OnBeforeSasl;
      //v1! Client.SetXmppDomain("chat.facebook.com");
      //v2! Client.XmppDomain = "chat.facebook.com";
      Client.Open();
    }

    private void xmppClient_OnBeforeSasl(object sender, Matrix.Xmpp.Sasl.SaslEventArgs e)
    {
      e.Auto = false;
      e.SaslMechanism = Matrix.Xmpp.Sasl.SaslMechanism.X_FACEBOOK_PLATFORM;
      e.SaslProperties = new Matrix.Xmpp.Sasl.Processor.Facebook.FacebookProperties
      {
        ApiKey = "xxxxxxxxxxxxx",
        ApiSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        SessionKey = AccessToken
      };
    }

No, there is not any debug log.
I found this topic how to get it http://forum.ag-software.de/thread/721-How-can-I-post-my-D…,
But I have not got any OnReadXml or OnWriteXm in my XMPPClient.

Then it does not connect at all to the Facebook server.

  • Are you using the correct dll for Mango?
  • Do you set all properties correct?
  • Are you on sockets and not on BOSH?

I suggest to play with the Desktop version and the MiniClient first with user, password login to Facebook. When this works then change to X_FACEBOOK_PLATFORM, when this works then port your code to WP7.

I have got this warning adding Windows Phone 7.1 Mango dll to my project.
And then this error

And another problem will be the following changes:
http://developers.facebook.com/blog/post/555/

When Facebook applies the API changes from there you will not be able to connect from WP7 anymore. Because there is no SslStream class in the Wp7.1 Framework. So we are no able to create Tls secured connections.

No, this means that you will not be able to connect to Facebooks XMPP service anymore when these changes go in production.

You still are able to connect to any other XMPP server on the XMPP network which does not require Tls. This is not a restriction of MatriX, the problem is that Microsoft does not allow us to create secure socket connection with the current version of the WP7.1 SDK.
