I am getting another problem. As far as I understand it, the background worker "finishes" when the DoWork callback has completed. I have a method that is called when the UI detects that the task is completed which is supposed to make sure the background worker doesn't get messed with when it is done. It is supposed to prevent cross-thread issues (the RunWorkerCompleted handler sets BackgroundWorker to null to try and prevent the exception below) while still making sure that the UI is updated and the worker "knows" it is supposed to be done. That method is below:

C#
public void End()
{
	if (BackgroundWorker != null)
	{
		if (BackgroundWorker.IsBusy)
			BackgroundWorker.ReportProgress(100);
		BackgroundWorker = null;
	}
}


However, the line with the call to ReportProgress crashes with this inner exception:
"This operation had OperationCompleted called on it and further calls are illegal"

First, if the operation has been completed, how come the handler for RunWorkerCompleted hasn't been called yet (I put a break in the handler's first line so I know this for certain)? Second, if the operation is completed, how can it be "busy"?
