MVCプロジェクトからWCFプロジェクトに画像をアップロードしています。 50 KB以下の画像ファイルでは問題ありませんが、50 KB以上では問題です。リモートサーバーからエラーが返されました：（413）要求エンティティが大きすぎます（毎週試されたソリューション）
私はすでにIISのsystem.webServer> serverRuntimeのUploadReadAheadSizeのサイズを52428800に増やしました。動作しませんでした。
WCF web.configファイルのすべてのバインディング構成の最大長を試しました。うまくいきませんでした。
WCF web.configファイルでMOTMエンコードタイプを試してみました。うまくいきませんでした。
以下は私の設定ファイルです。
