Summary

Part of the Task Scheduler 1.0 Interfaces, which consists of IEnumWorkItems, ITask, ITaskScheduler, ITaskTrigger and IScheduledWorkItem. There is some helper code below for actually using the iterator as the marshalling seemed impossible without resorting to the unmanaged helper functions in System.Runtime.InteropServices.Marshal. Not all methods have been tested, so be careful!

It is usually not necessary to call IUnknown's methods directly in your .NET code. The interop runtime code will insert the appropriate method calls for reference counting when the managed proxy objects are created and freed, and will translate typecast, "is", and "as" operators into calls to QueryInterface.
