title: Guid is all 0's (zeros)?
body: <p>I'm testing out some WCF services that send objects with Guids back and forth. In my web app test code, I'm doing the following:</p>
  
  <pre><code>var responseObject = proxy.CallService(new RequestObject
  {
      Data = "misc. data",
      Guid = new Guid()
  });
  </code></pre>
  
  <p>For some reason, the call to <strong>new Guid()</strong> is generating Guids with all 0's (zeros) like this:</p>
  
  <p><code>00000000-0000-0000-0000-000000000000</code></p>
  
  <p>What could be causing this?</p>
