title: java.util not working in visual studio 2010
body: <p>I was using java.util.zip for extracting zip files in c# visual studio 2005 project, </p>
  
  <p>but when I upgraded the project to visual studio 2010 it doesn't compile anymore and throwing following error</p>
  
  <pre><code>"The type or namespace name 'java' could not be found (are you missing a using directive or an assembly reference?)"
  </code></pre>
  
  <p>Is java or java.util is missing in visual studio 2010? What should I do to add this in my project?</p>
