title: How to create periodic task
body: <p>I have C# 2.0 codes that I am porting to C# 4.0. I want to make use of <code>System.Task</code> in place of the <code>System.ThreadPool.QueueueUserWorkItem</code>. I also want to make use of <code>System.Task</code> in place of <code>System.Threading.Timer</code>.</p>
  
  <p>How do I create a periodic <code>System.Task</code>? I do not see anything on <code>System.Task</code> or <code>System.TaskFactory</code>.</p>
  
  <p>Kind regards for consideration,</p>
