A background service runs long-running or periodic tasks asynchronously
This decouples these tasks from the main application logic, significantly improving application performance.
In C#, the easiest way to implement background services is by using the 𝗕𝗮𝗰𝗸𝗴𝗿𝗼𝘂𝗻𝗱𝗦𝗲𝗿𝘃𝗶𝗰𝗲.
This class is a base for long-running services and implements IHostedService.
Unlike IHostedService, which requires StartAsync and StopAsync methods, BackgroundService only requires the 𝗘𝘅𝗲𝗰𝘂𝘁𝗲𝗔𝘀𝘆𝗻𝗰 method, simplifying implementation.
Additionally, from .NET 8 we can run them concurrently as well.
For more complex scenarios, consider using 𝗤𝘂𝗮𝗿𝘁𝘇 or 𝗛𝗮𝗻𝗴𝗳𝗶𝗿𝗲.
