ASP.NET MVC 3（Razor）Ajax.ActionLink-我在做什么错？

<div id=\"admin-options\" class=\"admin\"></div>
@Ajax.ActionLink(\"Show Admin Options\", \"ShowOptions\", \"Post\", new { area = \"Admin\" }, new AjaxOptions { UpdateTargetId = \"admin-options\", HttpMethod = \"GET\" })

public class PostController : Controller
{
   [HttpGet]
   [Authorize(Roles=\"Admin\")]
   public PartialViewResult ShowOptions()
   {
      return PartialView();
   }
}

<a data-ajax=\"true\" data-ajax-method=\"GET\" data-ajax-mode=\"replace\" data-ajax-update=\"#admin-options\" href=\"/Admin/Post/ShowOptions\">Show Admin Options</a>

<script src=\"<%=Url.Content(\"~/Scripts/jquery.unobtrusive-ajax.min.js\")%>\" type=\"text/javascript\"></script>

<script src=\"@Url.Content(\"~/Scripts/jquery.unobtrusive-ajax.min.js\")\" type=\"text/javascript\"></script>
