title: Implementing TestSuite in NUnit
body: <p>I keep getting :</p>
  
  <pre><code>The type or namespace name 'TestSuite' could not be found (are you missing a using directive or an assembly reference?)
  </code></pre>
  
  <p>I use visual studio 2010 and I have installed the latest NUnit and selenium references via NuGet. Here is the code:</p>
  
  <pre><code>using NUnit.Framework;
  
  namespace SeleniumTests
  {
      public class ManifestTestSuite
      {
          [Suite] 
          public static TestSuite Suite
          {
              get
              {
                  TestSuite suite = new TestSuite("MyTestSuite");
                  suite.Add(new AddAll());
                  suite.Add(new RemoveAll());
                  return suite;
              }
          }
      }
  }
  </code></pre>
