title: When should I use Lazy<T>?
body: <p>I found this article about <code>Lazy</code>: <a href="http://sankarsan.wordpress.com/2009/10/04/laziness-in-c-4-0-lazyt/" rel="noreferrer">Laziness in C# 4.0 – Lazy</a></p>
  
  <p>What is the best practice to have best performance using Lazy objects?
  Can someone point me to a practical use in a real application? In other words, when should I use it?</p>
