title: OData v4 error on start-up: Resource not found for the segment 'Whatever'
body: <p>I am building out my new v4 service and all was going well until I added a new controller for a new model/entity and got this error when starting the site up for a test run.</p>
  
  <p>The controller seems to be correctly coded, just like the others.</p>
  
  <blockquote>
    <p>The path template 'Customers' on the action 'GetFeed' in controller 'CustomersOData' is not a valid OData path template. Resource not found for the segment 'Customers'.</p>
  </blockquote>
  
  <p>What on Earth does that mean?</p>
