Asp.NET Web application: run a method every x hours (long term)

Question

Is it possible to automate a method to run every x minutes/hours within a web application (server side of course)?

Simplified code:

public class Task
{
    public string Name { get; set; }
    public DateTime Deadline { get; set; }
    ...
}

The case: Each task has a deadline, I want to generate a mail if the deadline is approaching.

There are some answers, e.g. here with System.Threading or embed the functionality into a constructor. But how can I make sure, it will work for months without to be called?

Thank you!

Use a window service. IIS does not guarantee that a worker process is running in the absence of requests. — Wicher Visser, Jul 08 '16 at 12:02

My favorite tool for this is Hangfire. It lets you schedule tasks, your task would look like this:

RecurringJob.AddOrUpdate(() => CheckIfDeadlineIsApproaching(), Cron.Hourly);

Unlike the suggestions in the comments this doesn't require a Windows Service either, which makes this solution much easier.

You should put scheduler in application start. I think Global.asax.cs file

Who vote me down, you can look at any lib dos to make sure to run any persistent process, it should be placed in application start in web app. – Ebrahim Pasbani Jul 08 '16 at 12:15
