我在包管理器控制檯中更新我的數據庫時出現錯誤，這裏是我的配置類和web配置 角色管理器功能尚未啓用。 請幫我

MY配置類

namespace TechFactorsLMSV2.Migrations 
{ 
using System; 
using System.Data.Entity; 
using System.Data.Entity.Migrations; 
using System.Linq; 
using System.Web.Security; 
using TechFactorsLMSV2.Models; 
using WebMatrix.WebData; 

internal sealed class Configuration : DbMigrationsConfiguration<TechFactorsLMSV2.Models.LMSDBContext> 
{ 
    public Configuration() 
    { 
     AutomaticMigrationsEnabled = false; 
    } 

    protected override void Seed(TechFactorsLMSV2.Models.LMSDBContext context) 
    { 
     context.Schools.AddOrUpdate(d => d.SchoolName, 
       new School() { SchoolName = "School 1" }, 
       new School() { SchoolName = "School 2" }, 
       new School() { SchoolName = "School 3" } 
       ); 

     SeedMembership(); 
    } 

    private void SeedMembership() 
    { 
     WebSecurity.InitializeDatabaseConnection("DefaultConnection", 
      "UserProfile", "UserId", "UserName", autoCreateTables: true); 
     var roles = (SimpleRoleProvider)Roles.Provider; 
     var membership = (SimpleMembershipProvider)Membership.Provider; 

     if (!roles.RoleExists("Admin")) 
     { 
      roles.CreateRole("Admin"); 
     } 
     if (membership.GetUser("kadadmin", false) == null) 
     { 
      membership.CreateUserAndAccount("kadadmin", "password"); 
     } 
     if (!roles.GetRolesForUser("kadadmin").Contains("Admin")) 
     { 
      roles.AddUsersToRoles(new[] { "sallen" }, new[] { "admin" }); 
     } 
    } 
} 
}

<!-- 
    Enabling request validation in view pages would cause validation to occur 
    after the input has already been processed by the controller. By default 
    MVC performs request validation before a controller processes the input. 
    To change this behavior apply the ValidateInputAttribute to a 
    controller or action.

您需要根據本節的System.Web添加到Web.config

<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>
