This property is thread safe.
Changing IWorkbookSet.BackgroundCalculation from true to false stops background calculation before the property setter returns.
IWorkbookSet.BackgroundCalculation is on by default. However, background calculation will not be initiated if IWorkbookSet.Calculation is set to Calculation.Manual or if a lock is never acquired and subsequently released.
When utilizing background calculation, IWorkbookSet.GetLock must be used to acquire a lock before any access to any object in a workbook set.
All Windows Forms components from SpreadsheetGear use GetLock and IWorkbookSet.ReleaseLock whenever they access anything in a workbook set.
See IWorkbookSet.GetLock and IWorkbookSet.ReleaseLock for more information about acquiring and releasing locks as well as the effect this has on background calculation.
