待機操作がタイムアウトしました

Question

私はMVCコードの最初のアプリケーション開発に比較的新しく、VPSでMVCコードの最初のアプリケーションをホストしようとしました。アプリケーションを公開した後にウェブサイトを閲覧しようとしたときに、待機操作がタイムアウトになりました。私は少しの調査を行い、SQL上でTCP/IPを有効にすることを見つけた。 構成マネージャーが助けてくれたが、私は運がなかった。以下にスタックトレースが追加されています。

Answer 1

私はこれが誰かのために役に立つかもしれないと思うが、将来的に同じ過ちのための答えを探して来ました。

私の直面した問題は誰もが私のアプリケーションプールにユーザーを追加するのを忘れていたために助けてくれてありがとう！私の側から愚かな間違い！

Answer 2

私は同じ問題がありました。デフォルトのタイムアウトが30秒に設定されているため、一部のSQLアップグレードコマンドが非常に長く実行され、エラーが発生しました。私はこの問題を克服するために次の記事を見つけました： EF Code First - Timeout expired. The timeout period elapsed prior to completion

私にとって、CommandTimeoutはConfiguration.csファイルで180秒に設定されていました。

幸運
