HangFire gives you a simple way to kick off long-running processes from the ASP.NET request processing pipeline. Asynchronous, transparent, reliable, efficient processing. No Windows service/ Task Scheduler required. Even ASP.NET is not required.

Improve the responsiveness of your web application. Do not force your users to wait when the application performs the following tasks:

• mass notifications/newsletter;
• batch import from xml, csv, json;
• creation of archives;
• firing off web hooks;
• deleting users;
• building different graphs;
• image processing;
• …and so on.

Just wrap your long-running process to a method and instruct HangFire to create a background job based on this method. All backround jobs are being saved to a persistent storage (Redis, SQL Server or SQL Server + MSMQ) and performed on a dedicated worker thread in a reliable way inside or outside of your ASP.NET application.

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(
    @"Server=.\sqlexpress; Database=MyDatabase; Trusted_Connection=True;");

1. Enqueue a background job

You can run in background regular static or instance methods, just do the following:

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

2. Process it in background

Processing is made inside a different worker thread. To start the worker pool, call:

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

Please note, that these lines already added in the ~/App_Start/HangFireConfig.cs file for you.
