mvc4 Websecurity.login異常

Question

當我調用"WebSecurity.Login("UserName","Password",persistCookie:false)"

以下異常流

要調用此方法，“ Membership.Provider”屬性必須是“ ExtendedMembershipProvider”的實例

這是初始化連接的代碼：

private class SimpleMembershipInitializer
        {
            public SimpleMembershipInitializer()
            {
                    WebSecurity.InitializeDatabaseConnection("defaultDB", "User", "Id", "UserName", autoCreateTables: true);
            }
        }

下面是配置文件

在web.config設置以下代碼行：

<roleManager enabled="true" defaultProvider="SimpleRoleProvider">
        <providers>
            <clear />
            <add name="SimpleRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData" />
        </providers>
    </roleManager>
    <membership defaultProvider="SimpleMembershipProvider">
        <providers>
            <clear />
            <add name="SimpleMembershipProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
        </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>
