title: Visual Studio Build Events not equal condition
body: <p>Is there a way to have a not equal condition in build events ?</p>
  
  <p>Like this:</p>
  
  <pre><code>if $(ConfigurationName) != Debug xcopy ...
  </code></pre>
  
  <p>Note that this is build event (batch-like syntax), not MSBuild task (which indeed supports != ).</p>
