title: From where we can set "Build"or "Do Not Build" Contract reference for a project?
body: <p>I get following warning for almost all my projects in a solution:</p>
  
  <pre><code>Contract reference assembly for project 'X.X.X' not found. Select 'Build' or 'DoNotBuild' for Contract Reference in project settings.
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/5817061/code-contracts-build-reference-assembly-actions">Code contracts build reference assembly actions</a></p>
  
  <p>But I am unable to find any hint of from where we can set this option in visual studio.</p>
  
  <p>Any help on this much appreciated.</p>
  
  <p>Thanks and Regards</p>
