.NET Core Hosted Service: Practical Know How

A hosted service is a class with background task logic that implements the IHostedService interface. By implementing this interface you can create background tasks that run on a time interval, queued tasks that run sequentially or some sort of long running tasks. Implementing the interface is simple since there are two methods that need to be called: StartAsync() and StopAsync(). As the name implies, both are async methods so they simply need to return a Task. Problems that you can solve using Hosted Services are probably similar to the problems you currently solve using Windows Services or Azure WebJobs. While WebJobs have added benefit of being able to be deployed separately out of the box without conflicts and have additional functionality when it comes to running as a singleton. Windows Services are typically hosted on other infrastructure that isn’t also hosting your website. BackgroundService Helper has some sort of boiler plate which essentially implements IHostedService interface that fires your task on a different thread, and handles cancellation tokens etc. Apart from background task that runs on timer you can create scoped service or queued background task which is beyond the scope of this video. We will now see a quick demo of worker service template, the IHostBuilder which launches your task in Kestral server. Let's jump right in. I recommend you to download source code from the repository and create your hosted service and share your code in the comments section so everyone can benefit from it.
