Asp.Net Core 2.2 UseUrls is ignored

Question

I have the following code in my Asp.Net Core 2.2

public class Program
{
    public static void Main(string[] args)
    {
        var urls = new string[] { "https://localhost:3045" };
        CreateWebHostBuilder(args, urls).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args, string[] bindingUrls) =>
        WebHost.CreateDefaultBuilder(args)
            .ConfigureServices(services => services.AddAutofac())
            .ConfigureKestrel(opt =>
            {
                opt.AddServerHeader = false;
            })
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseUrls(bindingUrls)
            .UseStartup<Startup>();
}

However when I debug the site is launched on https://localhost:44326/ why is used in launchSettings.json Why is that happening?

Answer 1

.UseUrls(bindingUrls) will configure Kestrel url.

dotnet core always sits in Kestrel behind IIS / IIS Express as a proxy. The url you get is the configuration for your IIS Express .

This url can be changed in your project settings or launchSettings.json

If you would like to just run on Kestrel user the cli command dotnet run or dotnet watch run
