Answer 1

Another user had this exact issue, it was resolved using the following code:

var args = new Dictionary<string, object>(); 
 args["name"] = "Check this out"; 
 args["link"] = "www.xyz.com"; 
 args["caption"] = ""; 
 args["description"] = "description"; 
 args["picture"] = ""; 
 args["message"] = "Check this out"; 
 args["actions"] = ""; 

FacebookAsyncCallback callBack = new FacebookAsyncCallback(this.postResult); 
 fbApp.PostAsync("me/feed", args, callBack);   

    private void postResult(FacebookAsyncResult asyncResult) 
    { 
        System.Diagnostics.Debug.WriteLine(asyncResult); 
    } 

Post to Facebook wall using WP7 and Facebook.dll

ShareLinkTask shareLinkTask = new ShareLinkTask();
shareLinkTask.Title = "Divum Photo Browser";
shareLinkTask.LinkUri = new Uri(list_photos.ElementAt(index_).imageUrl, UriKind.Absolute);
shareLinkTask.Show();
