错误-98 EADDRINUSE地址已在Ubuntu上使用

Question

我刚刚使用https://github.com/omnisharp/generator-aspnet创建了简单的.NET核心webapi项目

然后尝试在Ubuntu子系统上运行应用程序.

当我跑步时,dotnet start我收到一个错误:

Unhandled Exception: System.AggregateException: One or more errors occurred. (Error -98 EADDRINUSE address already in use) ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -98 EADDRINUSE address already in use

   at Microsoft.AspNetCore.Hosting.WebHostExtensions.Run(IWebHost host)
   at WebApp.Program.Main(String[] args)

但是,当我在Windows上使用相同的命令运行应用程序时,cmd所有工作正常.

有什么想法如何解决？WebApi使用端口5000作为默认值.

更新:

我只是使用内联指定默认端口 .UseUrls("http://*:5000")

var host = new WebHostBuilder()
                .UseConfiguration(config)
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .UseStartup<Startup>()
                .UseUrls("http://*:5000")
                .Build();

所以现在它工作正常.但是我没有更改端口值. 有什么想法,为什么端口5000不在Ubuntu工作时没有指定？
