c# – 将MVC 4应用程序发布到天蓝色后的身份验证问题

我有一个基本的ASP.NET MVC 4网站,我在Azure网站上托管.身份验证是表单身份验证,还没有从默认模板中进行自定义.每次发布时,当我重新访问我的网站时,它会挂起很长的超时时间(几分钟),然后再显示一条错误信息.我可以通过删除我的浏览器中的网站的cookie并重新加载来恢复.

最初,问题只是尝试访问需要身份验证的页面,但是我将其添加到我的共享_Layout.cshtml中：

@if (User.IsInRole("Admin"))
{
    <li>@Html.ActionLink("Admin","Index","Admin")</li>
}

现在这意味着在新的发布之后,所有的页面都不可访问,所以我甚至不能单击退出链接,这是我以前能够解决问题的另一种方式.

有没有配置错误？虽然我有一个解决方法我可以使用自己,这不会是一个很好的经验,网站的用户发布更新后.

编辑：从ELMAH日志,当我调用IsInRole,似乎窗体身份验证正在尝试创建一个SQL Express数据库.我不明白为什么会这样做,因为我的表单身份验证全部设置为使用我的SQL Azure数据库.
