  <p>From my newly created Test project, I try to add a reference to my actual project. like this:
  <em>In Solution Explorer, select References in the BankTests project and then choose Add Reference... from the context menu.</em></p>
  
  <p>I get an error saying 'Unable to add a reference to project 'MyProject'.</p>
