Azureに公開すると、自分のASP.NET MVC4アプリケーションに問題があります。それは、私のローカル環境でのAzureに展開した後のMVCアプリケーションRoleManagerの問題

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

SQLExpress database file auto-creation error: 

The connection string specifies a local Sql Server Express instance using a database location within the application's App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database: 

If the application is running on either Windows 7 or Windows Server 2008R2, special configuration steps are necessary to enable automatic creation of the provider database. Additional information is available at: http://go.microsoft.com/fwlink/?LinkId=160102. If the application's App_Data directory does not already exist, the web server account must have read and write access to the application's directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist. 
If the application's App_Data directory already exists, the web server account only requires read and write access to the application's App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the application's App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server account's credentials are used when creating the new database. 
Sql Server Express must be installed on the machine. 
The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

興味深いことに:roleManager部分が動作していない、それが私の見解では、このコードに到達したときにアプリケーションがエラーを返します:

bool isAdmin = User.IsInRole("admin"); 

、エラーが以下の通りですうまく動作し、Azureでのみ発生します。 Azureに公開する場合は、web.configファイルの次のプロパティも再設定しました。しかし、ログインや登録など、アプリケーションの他の部分がうまく動作しているため、設定が不足していると疑いがあります。

接続文字列:

<connectionStrings> 
    <!--<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-Portal.mdf;Initial Catalog=aspnet-Portal;Integrated Security=True" providerName="System.Data.SqlClient" />--> 
    <add name="DefaultConnection" connectionString="Data Source=tcp:***,1433;Initial Catalog=***;Persist Security Info=False;User ID=***;Password=***;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" /> 
    </connectionStrings> 

そして、私のEntity Frameworkの構成:

<entityFramework> 
    <!--<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">--> 
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"> 
     <parameters> 
     <!--<parameter value="mssqllocaldb" />--> 
     <parameter value="Data Source=Data Source=***,1433;Initial Catalog=***;Persist Security Info=False;User ID=***;Password=***;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" /> 
     </parameters> 
    </defaultConnectionFactory> 
    <providers> 
     <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> 
    </providers> 
    </entityFramework> 

他configuratiがある場合、私は、思っていました私はAzureで動作するためにRoleManagerを変更する必要がありますか?

はあなたの時間と配慮をいただき、ありがとうございます。

個々のユーザーアカウントを使用してアプリケーションを作成した場合、既定では、以下のような「DefaultConnection」という名前の接続文字列がLocalDbを指すweb.configに追加され、Azure AppサービスWebアプリケーションに直接公開すると、 「SQL Serverへの接続を確立中にネットワーク関連またはインスタンス固有のエラーが発生しました」というエラーが表示されます。

<!--<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MVCAppWithRoleManager-20170630095851.mdf;Initial Catalog=aspnet-MVCAppWithRoleManager-20170630095851;Integrated Security=True" 
    providerName="System.Data.SqlClient" />--> 

あなたが行ったように、Azure SQLデータベースでDefaultConnectionを変更することができました。私の側では、ログインユーザー情報を取得し、ユーザーログイン後に現在のユーザーの役割を確認することができます。
