VS 2012 で MVC 4 Web アプリケーションを作成しました。NuGet 経由で Ext.Net 2 をダウンロードしました。私のview/home/index.cshtmlファイルで、次のように入力しようとしています:
@Html.X().ResourceManager()
実行すると次のようになります。
CS1061: 'System.Web.Mvc.HtmlHelper' には 'X' の定義が含まれておらず、タイプ 'System.Web.Mvc.HtmlHelper' の最初の引数を受け入れる拡張メソッド 'X' が見つかりませんでした (ディレクティブまたはアセンブリ参照を使用していますか?)
これが私のweb.configです
