将MVC 4应用程序发布到azure后的身份验证问题

Question

我有一个基本的ASP.NET MVC 4站点,我在Azure网站上托管.身份验证是表单身份验证,尚未从默认模板进行自定义.每次我发布时,当我重新访问我的网站时,它只会挂起很长的超时(也许是几分钟),最后会向我显示错误消息.我可以通过在浏览器中删除网站的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,但后来我将其添加到我的共享_Layout.cshtml:

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

现在意味着在新发布之后根本没有页面可访问,因此我甚至无法单击注销链接,这是我以前能够解决问题的另一种方式.

我有错误的配置吗？虽然我有自己可以使用的解决方法,但在发布更新后,这对于网站用户来说不是一个好的体验.

编辑:从ELMAH日志,似乎表单身份验证尝试在我调用IsInRole时创建SQL Express数据库.我无法理解为什么会这样做,因为我的表单身份验证都设置为使用我的SQL Azure数据库.

在尝试了各种博客文章中的数十种不同建议之后,我找到了一个解决方案.将InitialiseSimpleMembership属性添加到我的家庭控制器可以解决问题.

[InitializeSimpleMembership]
public class HomeController : Controller

在进行此更改后,我成功地管理了几个成功的发布.我怀疑原因是InitializeSimpleMembershipAttribute构造函数中的以下代码行需要在进行任何调用之前运行User.IsInRole:

WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);

我想最好的办法就是跑InitializeSimpleMembership进来Application_Start.
