Dotnet watch run --> using hostname?

sirthomas · March 8, 2019, 7:06pm

Hi everyone - quick question. I was wondering how to edit the dotnet watch run command to also bind to my hostname instead of just localhost.

I checked the github project and the readme doesn’t say much in that regard.

ie: http://mybox:5000/ & http://localhost:5000

.NET Core Apps binds to the hosts in the ASPNETCORE_URLS environment variable or whatever is configured using .UseUrls():

github.com

NetCoreTemplates/selfhost/blob/master/MyApp/Program.cs#L23




namespace MyApp
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseStartup<Startup>()
                .UseUrls(Environment.GetEnvironmentVariable("ASPNETCORE_URLS") ?? "http://localhost:5000/")
                .Build();


            host.Run();
        }
    }


    public class Startup : ModularStartup
    {
        public Startup(IConfiguration configuration) : base(configuration){}

This can also be configured in your launchSettings.json:

github.com

NetCoreTemplates/selfhost/blob/master/MyApp/Properties/launchSettings.json#L9


{
  "profiles": {
    "MyApp": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "applicationUrl": "http://localhost:5000/;https://localhost:5001/"
    }
  }
}

Excellent will try it now, thank you. I assumed it was an easy one. I have just started trying out the clean Templates/Bootstrap demo… not yet familiar with the different profile loading tools, hadn’t seen the json file.

public static IWebHost BuildWebHost(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
       .UseStartup<Startup>()
       .Build();
}
