fbSession Initialize for Frame

Nov 19, 2008 at 6:33 AM
FacebookClientSession fbSession = new FacebookClientSession(_apiKey, _secret);
if (fbSession.Initialize(this))
    _fbService = new FacebookService(fbSession);

I have a problem with this code the fbSession.Initialize(this) works only if this is a System.Windows.Forms.IWin32Window instance,
I'm using it for a mobile application, and for that i'm using another Class (don't know which exactly).

How can I overcome this problem?
Thanks a lot
