Configuring Rebus in a .net core Worker Service (or a Console App) - .net-core

Question

I have seen that Adding rebus in the ASP.NET Core execution pipeline is very neat using Startup.cs.
I wonder if there is a same neat way to do the same for Worker service or generally a console app.
Most .net core console apps I have seen are very simple demo applications.
Kindly if there is any concrete sample configuration using .net core console application.

One way would be to add Microsoft's Microsoft.Extensions.Hosting package and build your background service as a BackgroundService:
public class MyBackgroundService : BackgroundService
{
readonly IServiceCollection _services = new ServiceCollection();
public BackgroundService()
{
// configure the bus
services.AddResbus(
configure => configure
.Transport(t => t.Use(...))
);
}
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
using var provider = _services.BuildServiceProvider();
// start the bus
provider.UseRebus();
while (!stoppingToken.IsCancellationRequested)
{
await Task.Delay(TimeSpan.FromSeconds(1), stoppingToken);
}
}
}
which you then add by going
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<MyBackgroundService>();
});
in your startup.

Thanks Mogens,
Another way is to
var host =CreateHostBuilder(args).Build();
host.UseRebus();
host.Run();
Or in ConfigureServices method
....
var provider=services.CreateServiceProvider();
provider.UseRebus();
It helped me I could create Worker Services using rebus.
