ASP.NET Core “IHostedService Never Stops” — Fixing Broken Graceful Shutdowns

- 08.12.25 - ErcanOPAK

Many background workers never stop on SIGTERM.

✔ Real Fix

Bind cancellation token:

public Task StartAsync(CancellationToken ct)
{
    _ = DoWorkAsync(ct);
    return Task.CompletedTask;
}

💡 Super Tip

In Program.cs:

builder.Services.AddHostedService<MyWorker>();
builder.Services.Configure<HostOptions>(o =>
{
    o.ShutdownTimeout = TimeSpan.FromSeconds(20);
});

Most devs don’t know this exists → massively improves controlled shutdown.
