发布应用后,我无法启动dotnet core应用。 dotnet run在开发环境中启动应用程序时,尝试在发布后启动应用程序只会引发此错误。

这是我的Program.cs

namespace NiqVive.Api
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseKestrel(options =>
                    {                    
                        options.Listen(IPAddress.Any, 5007);
                        options.Limits.MaxRequestBodySize = null;
                    })

                .UseDefaultServiceProvider(options => {
                    options.ValidateScopes = false;
                });

    }
}

-硬件  版本:2.1.401

运行时环境:  操作系统名称:ubuntu  作业系统版本:18.04  RID:ubuntu.18.04-x64  基本路径:/usr/share/dotnet/sdk/2.1.401 /

如果我发布该应用程序,则不会开始。

转到“ Properties”文件夹并打开launchSetting.json文件,以其他方式更改端口号 在“ applicationUrl”:“ http://localhost:5001;http://localhost:4000”中,这里我们有http://localhost:5000将其更改为另一个端口
