Question

所以我在MVC3中构建了这个网站，我在其中使用用户，登录，角色等的默认ASP.NET成员资格提供程序。

最后是在线主持解决方案的时候，这给我带来了一些问题。

我已经通过sql脚本文件将我的SQL 2008 Express数据库迁移到托管数据库，该文件运行良好（有一些错误，但解决了它）。我可以正常渲染页面，并从数据库中加载数据。

问题是当我尝试使用现有用户登录或尝试创建新用户时。基本上任何使用成员资格提供程序存储过程的东西都会被抛出异常。

这是来自AccountController中标准登录功能抛出的尝试登录。

有关这些存储过程如何突然起作用的任何建议吗？

如果我尝试使用现有用户作为参数直接从数据库运行SP，它可以正常工作。它只是不会在网站的背景下工作。

来自AccountController的方法中的代码行失败：

MembershipUser user = Membership.GetUser(model.UserName);
