title: Is there XNOR (Logical biconditional) operator in C#?
body: <p>I'm new to C# and could not find <a href="http://en.wikipedia.org/wiki/Logical_biconditional" rel="noreferrer">XNOR</a> operator to provide this truth table:</p>
  
  <pre>
  a  b    a XNOR b
  ----------------
  T  T       T
  T  F       F
  F  T       F
  F  F       T
  </pre>
  
  <p>Is there a specific operator for this? Or I need to use !(A^B)?</p>
