Post Publish:

dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://www.example.com/article.html";
parameters.picture = "http://www.example.com/article-thumbnail.jpg";
parameters.name = "Article Title";
parameters.caption = "Caption for the link";
parameters.description = "Longer description of the link";
parameters.actions = new {
    name = "View on Zombo",
    link = "http://www.zombo.com",
};
parameters.privacy = new {
    value = "ALL_FRIENDS",
};
parameters.targeting = new {
    countries = "US",
    regions = "6,53",
    locales = "6",
};
dynamic result = client.Post("me/feed", parameters);
