ASP.Net 4.0 フレームワークで Web アプリケーションを作成し、データベースとのやり取りに MS-SQL を使用しています。コードをビルドし、共有 Web ホスティング サーバーにアップロードしました。そのホームページは正常に機能し、ページのコンテンツがデータベースと対話しない場合はすべてのページが正常に機能します。しかし、これらのページがデータベースと対話するページはエラーになります:

共有サーバーでこのエラーを解決するには??
すべてのコードはローカル IIS サーバーとテスト専用サーバーで正常に動作しますが、クライアントは共有サーバーを購入し、共有サーバーで実行したいと考えています。
この問題は、共有 Web ホスティング サーバーの「セキュリティ ポリシーで許可されていない操作をアプリケーションが実行しようとしました」に投稿されたスレッドに似ています。
しかし、その解決策は LINQ with ASP.NET です。ASP.NET を使用した MSSQL のソリューションが必要です
