BackgroundWorker class in ASP.NET simplifies background task handling by providing event-driven model and automatic thread management. It differs from other methods, such as ThreadPool or Task.Run, which require manual thread control and synchronization.
Choose BackgroundWorker when needing progress reporting, cancellation support, and separation of UI and worker threads without complex thread management. Prefer ThreadPool or Task.Run for short-lived tasks or scalable server applications where performance is critical.
