title: Why does Resharper rename variables to start with an underscore?
body: <p>I've never understood this, and frankly, it pisses me off to see it in code: variable names that begin with an underscore.</p>
  
  <p>What is the point of this?</p>
  
  <p>I've just installed Resharper 5.1, trying it out and it seems nice, though this one thing is ruining it for me.</p>
  
  <p>I haven't checked, but I'm hoping I can turn it off. But why is it done in the first place?</p>
