title: How to download file with Swagger UI
body: <p>I have rest controller which is returning HttpResponseMessage with Stream file as a content, something like this:</p>
  
  <pre><code>public class MyController : ApiController
  {
      public HttpResponseMessage GetFile(string id)
      {
          try { 
              var stream = fileSystemUtils.GetFileStream(filePath); //Get Stream
              HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
              response.Content = stream;
              return response;
          }
          catch (FileNotFoundException)
          {
              return new HttpResponseMessage(HttpStatusCode.NotFound);
          }
      }
  }
  </code></pre>
  
  <p>When i call this method by ULR in browser everything is ok and i can download this file. Now i would like to download it using Swagger UI. Is some easy way to do this?</p>
