title: Where is the CorrelationID in MVC 6
body: <p>How do I get the correlationID of a request using MVC 6? </p>
  
  <p>I want to use it when I log a message so that I can track a request through the system.</p>
  
  <p>In previous versions I would have used the HttpRequestMessageExtensions.GetCorrelationId method:
