框架Model注册失败

未知原因。全部推倒重来。

   public ActionResult Delete(int id)
        {
            if (!_permissionService.Authorize(StandardPermissionProvider.ManageBlog))
                return AccessDeniedView();

            var blogPost = _blogService.GetBlogPostById(id);
            if (blogPost == null)
                //No blog post found with the specified id
                return RedirectToAction("List");

            _blogService.DeleteBlogPost(blogPost);

            SuccessNotification(_localizationService.GetResource("Admin.ContentManagement.Blog.BlogPosts.Deleted"));
            return RedirectToAction("List");
        }
