title: What's the difference between dynamic (C# 4) and var?
body: <p>I had read a ton of articles about that new keyword that is shipping with C# v4, but I couldn't make out the difference between a "dynamic" and "var".</p>
  
  <p><a href="http://www.hanselman.com/blog/C4AndTheDynamicKeywordWhirlwindTourAroundNET4AndVisualStudio2010Beta1.aspx" rel="noreferrer">This article</a> made me think about it, but I still can't see any difference.</p>
  
  <p>Is it that you can use "var" only as a local variable, but dynamic as both local and global?</p>
  
  <p>Could you show some code without dynamic keyword and then show the same code with dynamic keyword?</p>
