TPL - ParallelUtility

Scenario:

Create utility to process data in parallel. Based on IDs, pull Users in parallel and then enqueue response and return back the list.

Solution:

ForEach takes list and Action to process the list and returns ParallelLoopResult. Add the result to ConcurrentQueue in thread safe visit. Then return/output list.
