You may want to ask, "What's the difference between a hosted service and a background thread?" The difference is that the hosted service will be started and stopped with the application. While, when starting a background thread, the thread cannot gracefully handle clean-up actions and will be killed when the application is stopped. The HostedServiceExecutor will handle the starting and stopping of a hosted service, which allows for graceful cleanup when the application is stopped.

Starts from version 2.1, .NET Core provides a native abstract base class BackgroundService, which includes common operations for background jobs such as CancellationToken and housekeeping works.
