.NET MVC Core 2部署问题IIS 10

Question

我正在尝试部署我的 asp.net MVC Core 2 站点到Windows Server 2016服务器2016服务器运行 iis 10 ，我是在应用程序日志中获取以下错误。

我已经研究了这个问题，并发现此.NET Core应用程序由于错误代码='0x80004005：80008083问题，该问题的答案是" vs2017 rc"，该问题已发货。SDK（.NET Core 1.0.4 SDK 1.0.1），您还需要在服务器上更新框架。"

运行以下命令显示了真实错误：

C:Windowssystem32>"C:Program Filesdotnetdotnet" C:inetpubwwwroot{YOUR_IIS_SITE_NAME}{YOUR_PROJECT_NAME}.dll

命令提示符的结果是以下内容告诉我我的连接字符串中有一个错误：

C:Windowssystem32>"C:Program Filesdotnetdotnet" C:inetpubwwwrootwww_projectx_comProjectX.dll

一旦解决了应用程序完美运行！

此外，请记住（在IIS上托管MVC Core应用程序时）以相应地更新您的程序。

public class Program
{
    public static void Main(string[] args)
    {
        BuildWebHost(args).Run();
    }
    public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();
}

最后但并非最不重要的一点是，我需要通过添加新创建的SQL用户来修复连接字符串（它不会简单地使用集成安全性来工作）：

"ConnectionStrings": {
    "DefaultConnection": "Server={theserver};Database={thedatabase};MultipleActiveResultSets=true;User Id={theusername};Password={thepassword};"
},
