问题 I have a requirement that background service should run Process method every day at 0:00 a.m. So, one of my team member wrote the following code: public class MyBackgroundService : IHostedService, IDisposable { private readonly ILogger _logger; private Timer _timer; public MyBackgroundService(ILogger<MyBackgroundService> logger) { _logger = logger; } public void Dispose() { _timer?.Dispose(); } public Task StartAsync(CancellationToken cancellationToken) { TimeSpan interval = TimeSpan

问题 I'm trying to write a simple web api project with a background service executing a method every second. This method loops over a list and just prints out (for the moment) some statistics. I declared a new list in the constructor of the background service. I'm currently encountering some issues with adding and removing items from inside the controller. public UsersController(IUserBackgroundService userService) { private readonly IUserBackgroundService _userService; public UserController

问题 I have a .NET Core 2.2 web API that can be scaled out to several instances based on demand. This API has a background service (IHostedService) that should only run on one of the instances at a time. Is there a common approach or design pattern to ensure this service is only running on one instance at any given point in time? 回答1: The ability to include a hosted service along with the actual application is just like anything else in Core. You can use all of MVC, API and Razor Pages, all in the

问题 I am creating a worker service which will be run as a windows service. I have a requirement where I would like to invoke two tasks which may have different timers. Say DoWork should be called every 5 minutes and DoAnotherWork should be called every 10 minutes or so. These two tasks can run in parallel and are not dependant on each other. I was able to create task DoWork which can run after every 5 minutes. I am a bit confused about how to implement another task that will have different timer

问题 I'm working with the HostBuilder in .NET Core (not the WebHost !). I have one Hosted Service running in my application that override the ExecuteAsync/StopAsync Method of the background Service and I want to unit test it. Here is my HostedService: public class DeviceToCloudMessageHostedService : BackgroundService { private readonly IDeviceToCloudMessageService _deviceToCloudMessageService; private readonly AppConfig _appConfig; public DeviceToCloudMessageHostedService

问题 I have faced a situation when Task.Delay() method would trigger an event of cancellation in IApplicationLifetime . Here is the code: static async Task Main(string[] args) { Console.WriteLine("Starting"); await BuildWebHost(args) .RunAsync(); Console.WriteLine("Press any key to exit.."); Console.ReadKey(); } private static IHost BuildWebHost(string[] args) { var hostBuilder = new HostBuilder() .ConfigureHostConfiguration(config => { config.AddEnvironmentVariables(); config.AddCommandLine(args)
