title: "Please correct before proceeding." - Web.config error
body: <p>I attempted to launch a website project locally but received the below message in an error dialog:</p>
  
  <blockquote>
    <p>Please correct before proceeding.(You might rename the current web.config and add a new one).</p>
  </blockquote>
  
  <p>Typically this error is preceded by a general description of the cause, this one was not.  Knowing odd, out-of-the-blue, problems such as these are typically related to corrupt IDE generated files. I tried deleting the <code>.suo</code>, <code>.vssscc</code> and other generated files from the solution and project directories but the problem continued.</p>
