Background Worker Example in C#

How to avoid application "not responding" ..? if you developed one application  for example require to read some big data in database, read big file, or do some complicated task, you need to execute that task in a background worker.

Background worker allow program do the task in a background process like picture above and wont let your application Not responding but actually the program is still work.

The BackgroundWorker class allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution.
