I noticed this on Mac. Whether I close or quit the desktop window, the HTTP service does not shut down.

Does the mechanism that I'm looking for exist and doesn't reliably function, or is it not there at all? Am I missing a part of configuration that relates? I don't believe that I have anything within my dotnet app that might be non-standard or in a way to preventing the backend console to die.

Thank you.

I've had the same problem on linux net core v3.1 and solved it by using OnClosed event from BrowserWindow object.

I injected IHostApplicationLifetime object in the Configure method and used StopApplication() when browser window called OnClosed event.

IHostApplicationLifetime is new in net core 3.0, before it was called IApplicationLifetime (ms doc)

For example:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IHostApplicationLifetime lifetime)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();
    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
    });

    Task.Run(() => BootstrapElectron(lifetime));
}

private async Task BootstrapElectron(IHostApplicationLifetime lifetime)
{
    var browserWindow = await Electron.WindowManager.CreateWindowAsync(new BrowserWindowOptions()
    {
        Show = false
    });

    browserWindow.OnReadyToShow += () =>
    {
        browserWindow.Show();
    };

    browserWindow.OnClosed += lifetime.StopApplication;
}

Thank you very much. That works flawlessly.

Previously, I had HTTP services remaining active in the background, and growing in number over time (as I would keep re-launching the app) - so, that wouldn't have looked good long-term.

Happy holidays!
