title: What's the relationship between Mono Cecil and NRefactory and how to compare them to Roslyn?
body: <p>I understand that Microsoft's Compiler as a Service or Roslyn project was inspired by Mono Cecil.</p>
  
  <p>But what's the relationship between Mono Cecil and NRefactory? Does one use the other? Or are they alternative technologies that do the same thing?</p>
  
  <p>It appears that both of them provide the same slew of code analysis services, just like Roslyn.</p>
