I found that some methods dont work at all .Ex. "SendNotification" method's signature is invalid. some one has to change raw XML data. facebook has changed its API, in dev kit ver 1.5,
signature is like >> SendNotification(string markup ,string tolist ,bool mail )
facebook changed the API and now signature should be
SendNotification(string tolist (i.e ids), string notifaction(FBML))
second thing is publishstory,publishaction has no effect,i couldnt see data publish through my app.
waiting for reply
