Hang when calling start/stop on IHost

The program below appears to hang after logging the application is shutting down message and I don’t understand why. The OnProcessExit event appears to be waiting here https://github.com/aspnet/Extensions/blob/master/src/Hosting/Hosting/src/Internal/ConsoleLifetime.cs#L79 but I don’t know why that would be or if that is a problem or just a red herring.

    public class Program
    {
        public static async Task Main(string[] args)
        {
            var host = CreateHostBuilder(args).Build();
            await host.StartAsync();
            await host.StopAsync();
        }

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

Yeah, we need to look at designing a real solution to this problem now.

It has nothing to do with background services. It’s all about the code in Program.cs that starts the host.
