title: Why can I get to use $format=json with entities but not with metadata using OData
body: <p>When I try this,</p>
  
  <pre><code>http://example.com/V3/OData/OData.svc/$metadata&amp;$format=json 
  </code></pre>
  
  <p>I get this error,</p>
  
  <blockquote>
    <p>"A supported MIME type could not be found that matches the acceptable
    MIME types for the request. The supported type(s) 'application/xml' do
    not match any of the acceptable MIME types
    'application/json;odata=verbose'."</p>
  </blockquote>
  
  <p>But when I try to access an entity like below it works,</p>
  
  <p><code>https://example.com/V3/OData/OData.svc/myExampleEntity?$format=json</code></p>
  
  <p><strong>Question</strong></p>
  
  <p>Why $format=json work with entities but not with metadata ?</p>
