title: Unable to apply a change while debugging
body: <p>I'm getting a strange error when attempting to debug a console app that's referencing a workflow service.</p>
  
  <p>'Unable to apply a change while debugging. Source file '...\myService\obj\Debug\TemporaryGeneratedFile_...cs' was reloaded. You must restart the debugging session.'</p>
  
  <p>I'm not doing anything out of the ordinary and this comes up as soon as I start debugging. There is a similar question here <a href="https://stackoverflow.com/questions/11391314/debugging-issue-in-vs2010">Debugging issue in VS2010</a> but the only answers suggest restarting visual studio/development server which hasn't helped me. Does anyone have a better explanation and or possible fix for this? I've tried restarting everything and looking into the temporary file referenced in the error message with no luck.</p>
