Asp.net mvc ASP.NET MVC4在开发计算机中，同时发生单击注销错误

我开发了asp.NETMVC4网站。我已经实现了CustomMembership和CustomRole功能。 单击注销按钮时出现错误 错误消息： 要调用此方法，“Membership.Provider”属性必须是“ExtendedMembershipProvider”的实例。

这是我的Web.Config文件

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <clear/>
    <add name="SimpleMembershipProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
    <add name="MyMembershipProvider" type="MvcApplicationTest.CustomMembershipProvider"
       connectionStringName="ApplicationServices" 
       enablePasswordRetrieval="false" 
       enablePasswordReset="true"  
       requiresQuestionAndAnswer="false"
       requireUniqueEmail="false"
       maxInvalidPasswordAttempts="5"
       minRequiredPasswordLenth ="6"
       minRequiredNonalphanumericCharacters="0"
       passwordAttemptWindow ="10"
       applicationName ="MvcApplicationTest.Client.Web"
         />
  </providers>
</membership>

<sessionState mode="InProc" customProvider="DefaultSessionProvider">
  <providers>
    <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" />
  </providers>
</sessionState>

<roleManager enabled="true" defaultProvider="MyRoleProvider">
  <providers>
    <clear/>
    <add name="SimpleRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData" />
    <add name="MyRoleProvider" type="MvcApplicationTest.Models.CustomRoleProvider"/>
  </providers>  
</roleManager>

谢谢，

您是否正在尝试实现ACL？CustomMembershipImplementing，当我单击LOGOFF时，它显示“error”调用此方法，“MembershipProvider”属性必须是“ExtendedMembershipProvider”的实例。请检查此项
