Was "Urls" in appsettings.json ignored in ASP.NET Core 6.0?

Question

In ASP.NET Core 6.0, is it no longer possible to override the Kestrel URL in appsettings.json > "Urls" as it was up to ASP.NET Core 5.0?

CustomUrlApp.csproj

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

</Project>

Program.cs

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/", () => "Hello World!");

app.Run();

appsettings.json

{
  "Urls": "http://*:5000;https://*:5001",
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*"
}

dotnet run's result.

Hi @Yuta Matsumura ,

To set the Kestrel specific endpoint configuration, you could use the following template in the appsettings.json file:

  "Kestrel": {  
    "Endpoints": {  
      "Https": {  
        "Url": "https://localhost:9999"  
      }  
    }  
  },  

The result is like this: it will override the configuration in the launchSettings.json file.
