title: How can I clear the cache of the workflow designer (where does it cache things)?
body: <p>Every time I change some <code>InArgument</code> of my <code>CodeActivity</code> or an activity defined as an XOML, it takes a couple of restarts of Visual Studio and deleting all the traces of my project's dll on the hard drive (not sure which part actually works) until the changes are reflected in the workflow designer.</p>
  
  <p>Is there some way to clear the cache of the workflow designer / Visual Studio so that the changes I have made for the activities are reflected immediately ?</p>
