1. Have not the function, also you can not changed the title value in a view. Because the html title is rendered on the top. But you can use the <title>@Page_Context.Current.HtmlMeta.HtmlTitle SiteName</title> instead of @Html.FrontHtml().HtmlTitle().
2.Where you got the "@Page_Context.Current.HtmlMeta.ContentTitle", it was changed to "@Page_Context.Current.ContentTitle", I think I forgot to make somewhere changed.
