Question

I want to change the default url ( http://localhost:5000 ) when i run the website as a console application .

I edited launchSettings.json but it doesn't work ... it still uses port 5000 :

    {
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:4230/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "website": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "http://localhost:80",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

You need to add the url when you build the "BuildWebHost". Hope this one helps you https://github.com/aspnet/KestrelHttpServer/issues/639

Below is the code I use in my .net core 2.0 console application

public class Program
{
    public static void Main(string[] args)
    {
        BuildWebHost(args).Run();
    }

    public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .UseUrls("http://localhost:5050/")
            .Build();
        
    
}
