A.
You should add a ProgressBar control to the form that hosts the BackgroundWorker component.

B.
You should apply the MTATThread attribute to the Main method of the application.

C.
You should apply the STATThread attribute to the Main method of the application.

D.
You should set WorkerReportProgress property of the BackgroundWorker class to true.
