Incredibly easy way to perform fire-and-forget, delayed and recurring jobs inside ASP.NET applications. No Windows Service / Task Scheduler required. Backed by Redis, SQL Server, SQL Azure or MSMQ.

HangFire provides 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/newsletter;
• batch import from xml, csv, json;
• creation of archives;
• firing off web hooks;
• deleting users;
• building different graphs;
• image/video processing;
• purge temporary files;
• recurring automated reports;
• database maintenance;
• …and so on.

HangFire is a .NET Framework alternative to Resque, Sidekiq, delayed_job.

See the Quick start guide to learn how to install and use HangFire for the first time.

HangFire is available as a NuGet package. So, install it using the NuGet Package Console window:

PM> Install-Package HangFire

After installing, open the ~/App_Start/HangFireConfig.cs file and modify the connection string:

JobStorage.Current = new SqlServerStorage("<name or connection string>");

Fire-and-forget tasks

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

Delayed tasks

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

Recurring tasks

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

Run them inside ASP.NET app…

Forget about AppDomain unloads, Web Garden & Web Farm issues – HangFire is reliable for ASP.NET from scratch, even on Shared Hosting!

var server = new AspNetBackgroundJobServer();
server.Start();

… or anywhere else

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

var server = new BackgroundJobServer();
server.Start();
