最近、WebAPI プロジェクトの EntityFramework を v5 から v6 に更新しました。残念ながら、何らかの形で、v5.0 に設定されている構成のどこかに存在する参照があるようです。私はそれを見つけることができないようです。以下に web.config を投稿します。
表示されるエラーは次のとおりです。
重複した「entityFramework」セクションが定義されています。
重複した参照は見つかりませんが、単一の参照を削除すると、次のエラーが表示されます。
{"メッセージ":"エラーが発生しました。"、"ExceptionMessage":"ファイルまたはアセンブリ 'EntityFramework、バージョン = 5.0.0.0、カルチャ = ニュートラル、PublicKeyToken = b77a5c561934e089' またはその依存関係の 1 つを読み込めませんでした。見つかったアセンブリのマニフェスト定義がアセンブリ参照と一致しません。(HRESULT からの例外: 0x80131040)","ExceptionType":"System.IO.FileLoadException","StackTrace":" System.Configuration.TypeUtil.GetTypeWithReflectionPermission(IInternalConfigHost ホスト、文字列 typeString、 Boolean throwOnError)\r\n at System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.Init(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord)\r\n System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.InitWithRestrictedPermissions(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord)\r\n System.Configuration.RuntimeConfigurationRecord.CreateSectionFactory(FactoryRecord factoryRecord)\r\n System.Configuration.BaseConfigurationRecord.FindAndEnsureFactoryRecord(String configKey, Boolean& isRootDeclaredHere)"}
これが私のweb.configです:

If you are deploying to a cloud environment that has multiple web server instances,
you should change session state mode from "InProc" to "Custom". In addition,
change the connection string named "DefaultConnection" to connect to an instance
of SQL Server (including SQL Azure and SQL Compact) instead of to SQL Server Express.
