. net核心逆向工程与数据库DNS连接

我的问题相当简单，我已经做了很多搜索的答案，但一直未能找到一个解决方案。这似乎不是一个不寻常的情况，然而，所以如果我忽略了一些简单的东西，或者有一个参考资料，我已经忽略了解决我的问题，我将非常感谢一些指导!这里是…

在尝试连接到一个现有的，离线数据库通过我的新。net Core项目。我在这里遵循逆向工程的说明:https://docs.efproject.net/en/latest/platforms/aspnetcore/existing-db.html

这些指令适用于本地机器上的数据库，但是当我使用连接字符串运行Scaffold-DbContext到离线服务器的数据库DNS时，它创建了上下文，但没有实体。所以我的context类文件是这样的

using System;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Metadata;
namespace CensusApi.Models
{
    public partial class CensusDbContext : DbContext
    {
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        #warning To protect potentially sensitive information in your connection string, you should move it out of source code. See http://go.microsoft.com/fwlink/?LinkId=723263 for guidance on storing connection strings.
        optionsBuilder.UseSqlServer(@"Server=database.dns.org,[port];Database=mydatabase;Integrated Security=False;User ID=myuser;Password=mypassword;");
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
    }
    // Unable to generate entity type for table 'dbo.LANDING_DEMOGRAPHICS_2010'. Please see the warning messages.
    // Unable to generate entity type for table 'dbo.LANDING_ECONOMIC_2007_2011'. Please see the warning messages.
    // Unable to generate entity type for table 'dbo.LANDING_STATE_FIPS'. Please see the warning messages.

    // Unable to generate entity type for table 'dbo.STAGE_ZIP_STATE'. Please see the warning messages.

    }
}

ErrorList窗口指向上面代码第11行中的#warning(即保护连接字符串中潜在敏感信息的警告)。我意识到进行此反向工程后的下一步是重新定位连接字符串，并且#warning似乎是一个通用警告，而不是对反向工程过程的阻碍。

我尝试的凭据包括sa用户和受限制的用户。两者都有相同的结果，所以这似乎不是权限问题。

是否有一个不同的方法或框架，我应该使用连接到外部服务器?

任何想法或反馈将非常感谢!
