How to get a second System.Thread.ThreadPool?

Question

If I use the ThreadPool in a nested way, my application hangs:

 ThreadPool.QueueUserWorkItem((state) =>
      ThreadPool.QueueUserWorkItem(Action));
         


        

Answer 1

You are using the wrong tools.

In .NET 4.0 they introduced the Task Parallel Library. This allows you to do things like use multiple thead pools as well as have parent-child relationships between work items.

Start with the Task class, which replaces ThreadPool.QueueUserWorkItem.

EDIT

Example of creating your own thread pool using Task and TaskScheduler.
