Overview

Incredibly easy way to perform fire-and-forget, delayed and recurring jobs in .NET applications. CPU and I/O intensive, long-running and short-running jobs are supported. No Windows Service / Task Scheduler required. Backed by Redis, SQL Server, SQL Azure and MSMQ.

Hangfire provides a unified programming model to handle background tasks in a reliable way and run them on shared hosting, dedicated hosting or in cloud. You can start with a simple setup and grow computational power for background jobs with time for these scenarios:

  • mass notifications/newsletters
  • batch import from xml, csv or json
  • creation of archives
  • firing off web hooks
  • deleting users
  • building different graphs
  • image/video processing
  • purging temporary files
  • recurring automated reports
  • database maintenance
  • …and so on

Hangfire is a .NET alternative to Resque, Sidekiq, delayed_job, Celery.

Hangfire Dashboard

Installation

Hangfire is available as a NuGet package. You can install it using the NuGet Package Console window:

PM> Install-Package Hangfire

After installation, update your existing OWIN Startup file with the following lines of code. If you do not have this class in your project or don't know what is it, please read the Quick start guide to learn about how to install Hangfire.

public void Configuration(IAppBuilder app)
{
    GlobalConfiguration.Configuration.UseSqlServerStorage("<connection string or its name>");
    
    app.UseHangfireServer();
    app.UseHangfireDashboard();
}

Usage

This is an incomplete list of features; to see all of them, check the official site and the documentation.

Fire-and-forget tasks

Dedicated worker pool threads execute queued background jobs as soon as possible, shortening your request's processing time.

BackgroundJob.Enqueue(() => Console.WriteLine("Simple!"));

Delayed tasks

Scheduled background jobs are executed only after a given amount of time.

BackgroundJob.Schedule(() => Console.WriteLine("Reliable!"), TimeSpan.FromDays(7));

Recurring tasks

Recurring jobs have never been simpler; just call the following method to perform any kind of recurring task using the CRON expressions.

RecurringJob.AddOrUpdate(() => Console.WriteLine("Transparent!"), Cron.Daily);

Continuations

Continuations allow you to define complex workflows by chaining multiple background jobs together.

var id = BackgroundJob.Enqueue(() => Console.WriteLine("Hello, "));
BackgroundJob.ContinueWith(id, () => Console.WriteLine("world!"));

Process background tasks inside a web application…

You can process background tasks in any OWIN-compatible application framework, including ASP.NET MVC, ASP.NET Web API, FubuMvc, Nancy, etc. Forget about AppDomain unloads, Web Garden & Web Farm issues – Hangfire is reliable for web applications from scratch, even on shared hosting.

app.UseHangfireServer();

… or anywhere else

In console applications, Windows Service, Azure Worker Role, etc.

using (new BackgroundJobServer())
{
    Console.WriteLine("Hangfire Server started. Press ENTER to exit...");
    Console.ReadLine();
}

Questions? Problems?

Open-source projects develop more smoothly when discussions are public.

If you have any questions, problems related to Hangfire usage or if you want to discuss new features, please visit the discussion forum. You can sign in there using your existing Google or GitHub account, so it's very simple to start using it.

If you've discovered a bug, please report it to the Hangfire GitHub Issues. Detailed reports with stack traces, actual and expected behaviours are welcome.

Please see the Extensions page on the official site.

Building the sources

Prerequisites:

  • Razor Generator: Required if you intend to edit the cshtml files.
  • Install the MSMQ service (Microsoft Message Queue Server), if not already installed.

Then, create an environment variable with Variable name Hangfire_SqlServer_ConnectionStringTemplate and put your connection string in the Variable value field. Example:

  • Variable name: Hangfire_SqlServer_ConnectionStringTemplate
  • Variable value: Data Source=.\sqlexpress;Initial Catalog=Hangfire.SqlServer.Tests;Integrated Security=True;

To build a solution and get assembly files, just run the following command. All build artifacts, including *.pdb files, will be placed into the build folder. Before proposing a pull request, please use this command to ensure everything is ok. Btw, you can execute this command from the Package Manager Console window.

build

To build NuGet packages as well as an archive file, use the pack command as shown below. You can find the result files in the build folder.

build pack

To see the full list of available commands, pass the -docs switch:

build -docs

Hangfire uses psake build automation tool. All psake tasks and functions defined in psake-build.ps1 (for this project) and psake-common.ps1 (for other Hangfire projects) files. Thanks to the psake project, they are very simple to use and modify!

Razor templates are compiled upon save with the Razor Generator Visual Studio extension. You will need this installed if you want to modify the Dashboard UI.

Reporting security issues

In order to give the community time to respond and upgrade we strongly urge you report all security issues privately. Please email us at security@hangfire.io with details and we will respond ASAP. Security issues always take precedence over bug fixes and feature work. We can and do mark releases as "urgent" if they contain serious security fixes.
