title: get 404 when trying to access files directly
body: <p>I have a WebApi project with a folder called "images".<br></p>
  
  <p>I want to access the images directly but I keep getting 404 with message "No type was found that matches the controller named 'images'."<br></p>
  
  <p>I did the same thing on MVC project and it always worked well, I don't know why in WebApi I can't access files.<br></p>
  
  <p>I'm sure the file is there, I see it in the directory.</p>
  
  <p>Example request: GET <a href="http://localhost:49873/images/20180704003126241.png" rel="nofollow noreferrer">http://localhost:49873/images/20180704003126241.png</a></p>
