title: How can I change my webservice's mime type?
body: <p>I have a rest service implementation as follows:</p>
  
  <pre><code> public string GetMenuItemById(string itemID)
   {
     MenuItemsRepository menutemsRepository = new MenuItemsRepository();
     string json = menutemsRepository.GetMenuItemById(itemID);
     .....
   }
  </code></pre>
  
  <p>I want to return JSON string, but the content-type in the response should not be application/json but text/json or html/json. How can I achieve this?</p>
