STAOperationBehavior
It is a PB customized operation attribute. Some functions like SaveDocument or Print involve many UI components, which require a thread running in STA (Single Thread Apartment) mode. But for IIS environment, the default thread mode of the WCF service operation is MTA (Multiple Thread Apartment). If a WCF operation uses such functions, you should define the "STAOperationBehavior" attribute for the operation.
