MSFT_WmiProvider_UnloadOperationEvent class
The MSFT_WmiProvider_UnLoadOperationEvent event class defines the removal of the provider cache entry. At this point there will be no reference held by WMI on the COM server instance. WMI caches provider registration objects to decrease overall execution time. The subsystem will drop cache entries either through the cache aging process, through loss of RPC connectivity, through user control or due to some change in the provider's registration.
The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.
