'Declaration
<ContentPropertyAttribute("Body")> _
Public NotInheritable Class ParallelForEach _
	Inherits NativeActivity
'Usage
Dim instance As ParallelForEach

The embedded statements are scheduled together and run asynchronously, but they do not run on separate threads so each successive activity will only execute when the previously scheduled activity completes or goes idle. If none of the child activities of this activity go idle, this activity execute in the same way that a ForEach activity does.so each successive activitiy will only execute when the previously scheduled activity completes or goes idle. If none of the child activities of this activity go idle, this activity execute in the same way that a Sequence activity does.. Unlike ParallelForEach(Of T), this element supports IEnumerable, and can iterate through non-generic lists.
