title: Specifing Alias for dll
body: <p>I have given an alias name to a dll which I am referencing from Visual studio by going to the property of that dll and specifing the alias and using the same in my code file.</p>
  
  <pre><code>extern alias toolkitalias;
  using toolkitalias::System.Windows;
  using toolkitalias::System.Windows.Controls;
  </code></pre>
  
  <p>But still it gives error saying  <strong>The extern alias 'toolkitalias' was not specified in a /reference option"</strong></p>
  
  <p>Am I missing something. Please help</p>
