私はasp.netのコアアプリケーションのためにユーザーのログインを促そうとしています。 Microsoftのチュートリアルhereに従ってください。私は、学校関連のすべてのモデルを保存するためのSchoolContextと、アカウントモデル用のApplicationDbContextという2つのコンテキストを持っています。これはすべてsqliteデータベースに保存されます。
私のコンテキストにユーザーを登録しようとするまで、すべてうまく動作します。ユーザーを登録しようとすると、AspNetUsersテーブルエラーが見つかりません。私がデータベースを見ると、AspNetUserテーブルは表示されません。私はmigrationsを追加しようとしましたが、私はまだ同じエラーが発生します。なぜテーブルが作成されていないのですか?Asp.netコア - そのようなテーブルはありません:AspNetUsers

[Users]テーブルが表示されますか?私の場合、1つのリクエストでUsersテーブルに書き込むこともできますが、次のリクエストでAspNetUsersから読み取ろうとします –
