Question

将ASP.NET MVC 4应用程序（代码优先）部署到IIS时出现以下错误：

“从数据库获取提供程序信息时发生错误。这可能是由实体框架使用不正确的连接字符串引起的。检查内部异常以获取详细信息，并确保连接字符串正确。“

我一直在寻找答案，但没有一种情况与我的相符：

我有2个项目

BackEnd（具有Code First + WCF服务的DataAccess）
FrontEnd MVC 4应用程序（仅对WCF服务的服务引用）

在我的本地IIS + SQL Server 2008上，它运行正常。即使我将连接字符串更改为生产数据库，一切都按预期工作。

将BackEnd + FrontEnd部署到IIS时会出现问题。

访问db的唯一连接字符串位于我的BackEnd应用程序中：
