New Post: COMException connecting to Windows 2012 Task Scheduler remotely

The property accessor task.Definition is throwing the exception:

System.Runtime.InteropServices.COMException (0x80041318): The task XML contains
a value which is incorrectly formatted or out of range. (Exception from HRESULT:
 0x80041318)
   at Microsoft.Win32.TaskScheduler.V2Interop.IRegisteredTask.get_Definition()
   at Microsoft.Win32.TaskScheduler.Task.get_Definition()

And task.Xml is:
