How can background tasks be executed from a library in an ASP.NET MVC 5 app

Question

In my job we are building Web Apps that rely on a common Enterprise class. This class has a method that sends a request to our server every time the app_start or app_end event triggers so we can monitor the status remotely. But we are now requiring that at least once a day the web app reports its status, a bit like telemetry. I don't know how to accomplish this, so far I have found some options, but some have limitations:

Use hangfire. I don't like this since it requires to setup a Database or add more tables and install a new Nuget package on each project, but could be my last option.
Use a Windows Service that reads databases. This could be less work but it can't access the Web App web.config code
Use a Javascript tasks that sends an AJAX request. This requires to have an open web browser and is a big risk.

I'm looking for a server side approach that could allow to set to trigger an event or function at 1am.

We used the IIS service auto start feature and during the app startup, we used a timer to do some cleanup at regular intervals. I guess the same thing can also be used in this case. — Thangadurai, Jun 21 '19 at 07:05

I would got with Hangifire.

It is dead easy to setup and very reliable. You don't need to setup the database, you might want to check memory storage:

You can use FluentScheduler instead of Hangfire (it is more lightweight).

Instead of a Javascript task that sends an AJAX request you can use a WebJob or an Azure Function.
