MVC4中的MySQLRoleProvider

如何在MVC4中使用MySQLRoleProvider？ MySQLProfileProvider和MySQLMembershipProvider工作正常，但Roles.IsUserInRolemyRole在VS2012 MVC4中不工作！总是很快回来

<profile defaultProvider="MySQLProfileProvider">
      <providers>
        <remove name="MySQLProfileProvider" />
        <add name="MySQLProfileProvider" type="MySql.Web.Profile.MySQLProfileProvider, MySql.Web, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" applicationName="\" description="" connectionStringName="LocalMySqlServer" writeExceptionsToEventLog="True" autogenerateschema="True" enableExpireCallback="False" />
      </providers>
    </profile>
    <roleManager defaultProvider="MySQLRoleProvider">
      <providers>
        <remove name="MySQLRoleProvider" />
        <add name="MySQLRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" applicationName="\" description="MyRoles description lwt" connectionStringName="LocalMySqlServer" writeExceptionsToEventLog="True" autogenerateschema="True" enableExpireCallback="False" />
      </providers>
    </roleManager>
    <membership defaultProvider="MySQLMembershipProvider">
      <providers>
        <clear />
        <remove name="MySQLMembershipProvider" />
        <add name="MySQLMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" applicationName="/" description="MySQL default application" connectionStringName="LocalMySqlServer" writeExceptionsToEventLog="True" autogenerateschema="True" enableExpireCallback="False" enablePasswordRetrieval="False" enablePasswordReset="True" requiresQuestionAndAnswer="True" requiresUniqueEmail="False" passwordFormat="Clear" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" />
      </providers>
    </membership>

您没有疯，这是目前已验证的错误：

这也让我发疯，直到我反编译dll以查看实现。

从MySql.NET Connector 6.9.6开始修复
