The graphi api profile_id/feed to post to a friend's wall is being deprecated. The blog https://developers.facebook.com/blog/post/2012/10/10/growing-quality-apps-with-open-graph/ directs that the feed/dialog should be used.
How can the feed/dialog be utilized in a Windows 8 application? If it cannot how can a post to a friend's wall be done in a Windows 8 application?
