title: activity could not be loaded because of errors in the XAML
body: <p>Considering the following scenario:</p>
  
  <ol>
  <li>Create MyCodeActivity1 with argument MyArgument1</li>
  <li>Add this activity to a myworkflow.xaml</li>
  <li>Rename MyArgument1 in MyCodeActivity1 to MyRenamedArgument1</li>
  </ol>
  
  <p>If you open myworkflow.xaml, visual studio will show this error:<br/></p>
  
  <blockquote>
    <p>activity could not be loaded because of errors in the XAML</p>
  </blockquote>
  
  <p>Is there a facility where visual studio can give more information about the error please?
  For now I have created a small windows application that tries to execute the workflow and shows an error message if invalid. This does give a clear message. But it would be great if visual studio provided this functionality directly.</p>
