title: How do I pass data between activities in Windows Workflow?
body: <p>I'm not completely sure I understand the workflow way of doing things, but if it's a pipeline n filter style model I should be able to pass data (even strings) from one activity to another. </p>
  
  <p>Does anyone know how to do this? Bonus points for a video!</p>
  
  <p>I hope this is possible. If WF were the same as my idea of it then it would be extremely useful.</p>
