次のアドバイスを使用して、カスタム メンバーシップ プロバイダーを構成しようとしています: Custom MembershipProvider in .NET 4.0

私の環境：VS2012、ASP.NET NVC4インターネットアプリケーション（ウィザードで作成）。私の目標は、外部データ ストアでユーザーを管理することです。

プロバイダー コードを追加した後... web.config のセクションに次のセクションを追加しました。

 <membership defaultProvider="MyMembershipProvider">
  <providers>
    <clear/>
    <add name="MyMembershipProvider" type=" MvcApplication2.Models.MyMembershipProvider" connectionStringName="DefaultConnection"
         enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false"
         maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10"
         applicationName="/" />
  </providers>
</membership>

アプリをデバッグしようとした後、次のエラーが発生しました。

Server Error in '/' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. 

Parser Error Message: This method cannot be called during the application's pre-start initialization phase.

Source Error: 


Line 41:       <providers>
Line 42:         <clear/>
Line 43:         <add name="MyMembershipProvider" type="MvcApplication2.Models.MyMembershipProvider" connectionStringName="DefaultConnection"

この記事のアドバイスに従おうとしました: ASP.NET: このメソッドは、アプリケーションの開始前の初期化段階で呼び出すことはできません。

残念ながら、説明どおりに設定を追加した後：

 <add key="enableSimpleMembership" value="false"/>

アプリが起動しますが、ログインを押した後、Visual Studio で次の例外が発生します。
