title: Empty String Literal
body: <p>I have come across some code during a code-review where a old coworker has done the following:</p>
  
  <pre><code>const string replacement = @""; 
  </code></pre>
  
  <p>This string is used in a regex expression as a replacement for what is matched. My question is what is the purpose of adding the @ literal sign to the beginning of an empty string. There should not be anything to literally interpret.</p>
  
  <p>Would there be any difference in impact between: <code>@"";</code> and  <code>"";</code>?</p>
