已将ASP MVC5站点部署到Azure，获取500内部服务器错误

我使用本地数据库在本地构建了一个ASP.NET MVC5网站。我想把它带到azure web服务上，所以我启用了一个azure网站，并设置从Visual Studio Online Git回购进行部署。部署已进行，但访问页面只会生成"处理请求时出错"错误

如果我查看日志，我会得到以下错误列表：

1. 模块响应错误状态

Warning ModuleName="ManagedPipelineHandler"，通知="EXECUTE_REQUEST_HANDLER"，HttpStatus="500"，HttpReason="内部服务器错误"，HttpSubStatus="0"，ErrorCode="操作已成功完成。（0x0）"，ConfigExceptionInfo="

数据库的连接字符串已替换为AzureSqlDatabase连接字符串，因此我尝试在那里进行检查。字符串"看起来"很好，但我注意到，当我在调试模式下运行应用程序时，它以某种方式使用了原始的本地Sql数据库，尽管该连接字符串已不在代码中！

我尝试了SO中列出的一些建议，包括启用详细的日志记录和重新推送web.config文件，但似乎都不起作用。关于如何追踪和解决这个问题，有什么想法吗？

编辑：在MFanto的帮助下，我发现该应用程序仍在以某种方式使用旧的本地SQL数据库的连接字符串。（数据源=.''SQLEXPRESS；初始目录=HouseOfBurt.Models.DataContext；集成安全性=True；MultipleActiveResultSets=True）

Web.config如下所示：

Web.Debug.Config（当然修改了密码）

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

    In the example below, the "SetAttributes" transform will change the value of

      <customErrors defaultRedirect="GenericError.htm"

EDIT2：添加DbContext类：

public class DataContext : DbContext
    {
        #region Tables
        public DbSet<Article> Articles { get; set; }
        public DbSet<Category> Categories { get; set; }
        public DbSet<Link> Links { get; set; }
        #endregion Tables
        #region Public Methods
        #endregion Public Methods
    }
