Dear All,

Please help me to sort one of my doubts regarding Release of Un-Managed Objects. If we are not explicitly calling dispose/close method for un-managed objects neither we are implementing finalizer for this unmanaged objects then what will happened for this unmanaged objects. Whether Operating system will take care after some time to release it or it will stay there till Operating system shouldn't get restarted. Please share...
