title: Task Parallel Library and IIS worker Threads?
body: <p>I want to use Task Parallel Library for some calculation intensive tasks, but I have been told by a colleague there is a huge overhead for IIS creating worker threads.</p>
  
  <p>I am not sure quite what is done when you call Task.Factory.StartNew()...say 100 times. How does IIS handle this? Is is a huge risk, or is there ways to make this very beneficial for an application?</p>
