IISにMVCプロジェクトを展開した後に500（内部サーバーエラー）

Question

私のMVCプロジェクトはVS2015（LocalDB + IISexpress）でもうまくいきますが、このプロジェクトではEntityFrameworkも使用しています。

目標：。は今、私は地元のIISに公開してみたい（ver.10） それから私は、2016年 のMicrosoft SQL Management Studioでデータベースを添付私はIISでプロジェクトを追加しました。

問題： APIコントローラを呼び出すと、500エラーが返されます。

web.configファイルで私の接続文字列は次のとおりです。

"接続文字列" の設定、デプロイ後の接続文字列は次のようになりますでIISで

<connectionStrings> 
<add name="UserDBEntities" connectionString="metadata=res://*/UserDbEntities.csdl|res://*/UserDbEntities.ssdl|res://*/UserDbEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(LocalDB)\MSSQLLocalDB;attachdbfilename=|DataDirectory|\UserDB.mdf;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 
</connectionStrings> 

：

metadata=res://*/UserDbEntities.csdl|res://*/UserDbEntities.ssdl|res://*/UserDbEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=(LocalDB)\MSSQLLocalDB;attachdbfilename=|DataDirectory|\UserDB.mdf;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework" 

私が変更唯一のソースからソース=（LocalDB）\ MSSQLLocalDB〜ソース= DesktopName \ MSSQLSERVER2016

Answer 1

Visual Studioでデータベースを開くことができる場合は、SQL Serverオブジェクトエクスプローラーウィンドウでデータベースを右クリックし、[プロパティ]を選択します。プロパティペインには、接続文字列のある行があります。

そうでない場合は、手動で接続文字列を構築する必要があります、SQL Serverの、おそらくのようなものになります。

Data Source=[host];Initial Catalog=[DB];Integrated Security=False;User Id=[user];Password=[password];MultipleActiveResultSets=True
