Graceful shutdown with Generic Host in .NET Core 2.1

Question

.NET Core 2.1 introduced new Generic Host, which allows to host non-HTTP workloads with all benefits of Web Host. Currently, there is no much information and recipes with it

Answer 1

In Startup.cs, you can terminate the application with the Kill() method of the current process:

        public void Configure(IHostApplicationLifetime appLifetime)
        {
            appLifetime.ApplicationStarted.Register(() =>
            {
                Console.WriteLine("Press Ctrl+C to shut down.");
            });

            appLifetime.ApplicationStopped.Register(() =>
            {
                Console.WriteLine("Shutting down...");
                System.Diagnostics.Process.GetCurrentProcess().Kill();
            });
        }

Program.cs

Don't forget to use UseConsoleLifetime() while building the host.

Host.CreateDefaultBuilder(args).UseConsoleLifetime(opts => opts.SuppressStatusMessages = true);
