How to stop/exit/terminate dotnet core HostBuilder console application programmatically?

To stop/exit/terminate a .NET Core HostBuilder console application programmatically, you can make use of the IHostApplicationLifetime interface provided by the Microsoft.Extensions.Hosting.Abstractions package.

Here's an example of how you can use it:

using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Hosting; using System; using System.Threading; using System.Threading.Tasks; namespace ConsoleApp { class Program { static async Task Main(string[] args) { var hostBuilder = new HostBuilder() .ConfigureServices((hostContext, services) => { services.AddSingleton<IHostLifetime, ConsoleLifetime>(); services.AddHostedService<MyService>(); }); await hostBuilder.RunConsoleAsync(); } } public class MyService : IHostedService { private readonly IHostApplicationLifetime _appLifetime; public MyService(IHostApplicationLifetime appLifetime) { _appLifetime = appLifetime; } public Task StartAsync(CancellationToken cancellationToken) { Console.WriteLine("MyService started."); // Stop the application after 5 seconds _appLifetime.StopApplication(); return Task.CompletedTask; } public Task StopAsync(CancellationToken cancellationToken) { Console.WriteLine("MyService stopped."); return Task.CompletedTask; } } internal class ConsoleLifetime : IHostLifetime { private readonly TaskCompletionSource<object> _delayStart = new TaskCompletionSource<object>(); public Task WaitForStartAsync(CancellationToken cancellationToken) { cancellationToken.Register(() => _delayStart.TrySetCanceled()); return _delayStart.Task; } public Task StopAsync(CancellationToken cancellationToken) { return Task.CompletedTask; } } }

In this example, the MyService implements the IHostedService interface and injects the IHostApplicationLifetime interface in the constructor. The StartAsync method sets a delay of 5 seconds and then calls the _appLifetime.StopApplication() method to stop the application.

The ConsoleLifetime class implements the IHostLifetime interface, which is responsible for starting and stopping the host. The WaitForStartAsync method returns a Task that completes when the host is started. The StopAsync method is called when the host is stopped, and it returns a completed Task.
