Describe the bug

ConsoleLifetime clobbers any exit code set by calling Environment.Exit()

To Reproduce

Program.cs:

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleLifetimeTest
{
    public class ApplicationHostedService : IHostedService
    {
        public Task StartAsync(CancellationToken cancellationToken)
        {
            new Thread(() =>
            {
                Thread.Sleep(500);
                Environment.Exit(123);
            }).Start();
            return Task.CompletedTask;
        }

        public Task StopAsync(CancellationToken cancellationToken)
        {
            return Task.CompletedTask;
        }
    }

    static class Program
    {
        public static void Main(string[] args)
        {
            using (var host = CreateHostBuilder(args).Build())
                host.Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddHostedService<ApplicationHostedService>();
                });
    }
}

ConsoleLifetimeTest.csproj:

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Hosting" Version="3.1.6" />
    <PackageReference Include="Microsoft.Extensions.Hosting.Abstractions" Version="3.1.6" />
  </ItemGroup>

</Project>

Steps to reproduce the behavior:

  1. Run code above
  2. Process exits with code 0

Expected behavior

Process to exit with code 123

Additional context

The change in this PR seems to be responsible, explicitly setting Environment.ExitCode to 0: dotnet/aspnetcore#6526

    It looks like we're setting the value to 0 by default and should maybe be checking for 143 instead

    runtime/src/libraries/Microsoft.Extensions.Hosting/src/Internal/ConsoleLifetime.cs

    Line 89 in 6faf435

    System.Environment.ExitCode = 0;
