我正在尝试将 asp.net 4.5 mvc4 应用程序部署到内部服务器。构建文件在服务器上，但尝试访问该站点会产生以下错误：

我认为这与我的连接字符串有关：

<add name="MyDatabase" connectionString="data source=Server;initial 
catalog=MyDatabase;User Id=App;Password=some password;"
providerName="System.Data.SqlClient"/>

好的，所以问题是 UsersContext 仍在使用默认连接字符串。我只需要将基本上下文更改为我的连接字符串。

public class UsersContext : DbContext
{
    public UsersContext()
        : base("MyDBContext")
    {
    }

    public DbSet<UserProfile> UserProfiles { get; set; }
    public DbSet<webpages_Membership> webpages_Memberships { get; set; }
    public DbSet<UsersInRole> webpages_UsersInRoles { get; set; }
    public DbSet<Role> webpages_Roles { get; set; }
}

但请注意，我遇到了 UsersContext 表和我自己的连接字符串的超时问题。在使用此修复程序之前，您可能需要查看此主题： SimpleMembership MVC 4保持身份验证，但未通过身份验证

我通过注释文件过滤器FilterConfig.cs InitializeSimpleMembershipAttribute 中出现的行解决了这个问题。我认为它必须先执行我不使用的代码，并且它连接到我在出版物中拥有的文件。

1）该服务器名称（服务器）是否正确？这是您在 SQL Management Studio 或 Visual Studio 中连接到它时看到的名称吗？SQL Server 是什么版本和版本？

2) 连接字符串参数是否在 UDL 文件中起作用？

3) 检查连接字符串是否符合您的预期。我在下面提供了一个使用 log4.net 记录连接字符串的示例，但是您可以在此处放置断点或写入文本文件。

m_log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType );
foreach( var connectionString in System.Configuration.ConfigurationManager.ConnectionStrings )
{
    string outString = connectionString.ToString();
    m_log.Debug( outString );
}
