title: The namespace '<global namespace>' already contains a definition for 'Workflow'
body: <p>I'm working on a Custom workflow activity.  I've created my own helper.cs (Early Bound Entity Classes) with the Code Generation Tool (CrmSvcUtil.exe)</p>
  
  <p>When I try to compile the code, it returns the following error: </p>
  
  <blockquote>
    <p>The namespace '' already contains a definition for 'Workflow' </p>
  </blockquote>
  
  <p>From the Helper.cs file.</p>
  
  <p>Does anyone know what this means? </p>
