![]() Here is an example that illustrates the configuration of a hosted service. It provides the logic to end the background task. ![]() StopAsync(CancellationToken): called before the application stops. StartAsync(CancellationToken): provides the logic to start the background task. The IHostedService interface contains two methods: Even Kestrel, the ASP.NET Core server, runs as an IHostedService. When the application stops, the services are stopped as well. When the application starts, you register multiple background tasks that run in the background while the application is running. The hosted service simply indicates a class that contains background task logic. You can use the IHostedService interface to run tasks in the background. In ASP.NET Core, these types of background tasks are called Hosted Services, because you host them within your application. An easy and reliable way to perform fire-and-forget, delayed and recurring, long-running, short-running, CPU or I/O intensive tasks inside ASP.NET applications. For example, when a user signs up, instead of sending them an email in the same request, you can schedule a background job that will send the email to the user.ĪSP.NET Core supports background tasks, by providing an abstraction for running a task in the background when the application starts. Rather, they run in the background, handling items from a queue or executing a long-running process.Ī primary advantage of performing these tasks in a background job or service, you can keep the application responsive. These jobs are not meant to interact with the customers or process user input. Do you use anything like that? I suggest sharing your thoughts in comments.Background tasks, also called as jobs, are essentially services that aren’t meant to execute during a normal flow of the application, such as sending email confirmations or periodically cleaning up the database to purge the inactive accounts. It is a free and public service, which cuts costs on development and maintenance of distributed systems. DefaultConnection is a connection string name, added to appsettings.json file. We must provide a connection string to locate SQL Server database named HangFireDb. Here, we are registering Hangfire with SQL Server. Services.AddHangfire(x => x.UseSqlServerStorage(Configuration.GetConnectionString("DefaultConnection"))) On top of that it supports persistence, so all of your tasks will continue to exist even after restarting your app. It supports one-off 'fire and forget' tasks, as well as scheduling recurring tasks. public void ConfigureServices(IServiceCollection services) NET library that makes it really easy to adding background tasks to your. Open Startup.cs class and locate a ConfigureServices method to register Hangfire as a service. Install via command PM> Install-Package HangFire Hangfire creates background jobs in persistence storage, like MS SQL Server, Redis, MongoDb, and others, that may prevent you from from losing the job on recycling IIS pools or exception prevalence. You'll be able to create a simple background process inside the same application pool or thread without creating separate applications. Hangfire is an open source library to schedule and execute background jobs in. In this article, we are going to setup Hangfire and write some code to schedule an initial job in the ASP.NET Core project. ![]() Hangfire is a multi-threaded and scalable task scheduler built on client-server architecture on. ![]()
