问题描述
我在写使用Microsoft Visual Studio EX preSS 2012年网的MVC4网站。 每当我在运行程序包管理器控制台更新-数据库，以下异常情况：
调用此方法时，Membership.Provider属性必须是实例 的ExtendedMembershipProvider。
这是我种方式：
保护覆盖无效种子（GNSystem.Models.DataContext上下文）
{
context.Forums.AddOrUpdate（
新论坛{ForumName =你好}，
新论坛{ForumName =世界}，
新论坛{ForumName =！ }
）;
context.UserProfiles.Add（新UserAccount {用户名=吉拉德，电子邮件=gilad.doom@gmail.com}）;
WebSecurity.CreateUserAndAccount（吉拉德，123456）;
WebSecurity.Login（吉拉德，123456）;
context.Threads.AddOrUpdate（
新的主题{主题=FirstThread，内容=真棒内容，ForumID = 1，用户名= 1}，
新的主题{主题=SecondThread，内容=真棒内容，ForumID = 1，用户名= 1}
）;
}
我搜索<一个href="http://www.asp.net/web-pages/tutorials/security/16-adding-security-and-membership">solutions并增加在Web.config文件中的以下指令：

解决方案
在您可以使用 WebSecurity.CreateUserAndAccount（吉拉德，123456）; SimpleMembership必须初始化。这通常是在的AccountController与 [InitializeSimpleMembership] 属性，但因为你想打电话给你的种子中的这些方法，你将需要初始化它的另一种方式。
I'm writing a MVC4 Website using Microsoft Visual Studio express 2012 for web. Whenever I run "Update-Database" in the Package Manager Console, the following Exception occurs:
To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".
This is my Seed method:
protected override void Seed(GNSystem.Models.DataContext context)
{
context.Forums.AddOrUpdate(
new Forum { ForumName = "Hello" },
new Forum { ForumName = "World" },
new Forum { ForumName = "!" }
);
context.UserProfiles.Add(new UserAccount { UserName = "Gilad", EMail = "gilad.doom@gmail.com" });
WebSecurity.CreateUserAndAccount("Gilad", "123456");
WebSecurity.Login("Gilad", "123456");
context.Threads.AddOrUpdate(
new Thread { Subject = "FirstThread", Content = "Awesome Content", ForumID = 1, UserID = 1 },
new Thread { Subject = "SecondThread", Content = "Awesome Content", ForumID = 1, UserID = 1 }
);
}
I searched for solutions and added the following directive in the Web.config file:
<add key="enableSimpleMembership" value="true" />
but the exception is thrown nonetheless.
What is the cause of this? Edit 1:

解决方案
Before you can use WebSecurity.CreateUserAndAccount("Gilad", "123456"); SimpleMembership must be initialized. This is typically done on the AccountController with the [InitializeSimpleMembership] attribute, but since you're trying to call these methods within your Seed, you will need to initialize it another way.
