Task Scheduler Managed Class Library

Microsoft.Win32.TaskScheduler Namespace

The Microsoft.Win32.TaskScheduler namespace provides a wrapper for the 1.0 and 2.0 versions of Task Scheduler found in all Microsoft operating systems post Windows 98. It will automatically choose the most recent version of the library found on the host system. The namespace includes classes for direct manipulation of the Task Scheduler as well as UI items to allow users to manipulate tasks.
