title: Get a graphical representation of a C# code logic - method calls hierarchy
body: <p>My actual work consists in some refactoring/code cleanup of parts of a big C# project.</p>
  
  <p>To allow a better understanding of the code logic, and so wich part of the code could be refactorized, I imagine a good way could be to see "graphically" wich methods call wich methods.</p>
  
  <p>If this a good approach ?</p>
  
  <p>And if yes, Is there such a tool ?
  The top of the top would be a free tool but if it don't exists, i could make an effort ^^</p>
  
  <p>I came across DebuggerCanvas and something like this but automatic (like using DebuggerCanvas and go into ALL the methods would be the idea)</p>
  
  <p>Thank's by advance.</p>
