多くの人と同じように、Web サイトがリモート サーバーに展開されると、Web サイトにログインできなくなります。Microsoft のドキュメント「ウォークスルー: メンバーシップとユーザー ログインを使用して Web サイトを作成する」を使用し、メンバーシップ機能を使用するために必要なものはすべて、生成された ASPNETDB.MDF ファイルに含まれると考えました。誰かがなぜそれが機能しないのかを理解するのを手伝ってもらえますか? メンバーシップを使用するのはこれが初めての試みです。
デプロイ時にログインしようとすると、次のエラーが表示されました (ログイン ボタンを押してもデータベースにはアクセスせず、「メニュー画面」にアクセスするだけであることに注意してください)。

私は他のすべての投稿を見て、できる限り多くの他の解決策を試しました（そうです）。ある人が示唆したように、web.config ファイルから LocalSqlServer を削除しようとしたところ、エラーが発生しました。

それで、次に LocalSqlServer を追加しようとして、それを使用しようとしていてできないと思ったのですが、再びエラーが発生しました。

最後に、以下は私の web.config ファイルです (上記のコードは追加されていません):

ご協力いただければ幸いです。何が間違っているのかを理解しようと 2 日間費やしましたが、コードは自動的に生成されたので、何をしているのかわかりません。
