How to post both JSON and XML data at same time using body- form data?

you can design the API to accept both types as shown below but HTTP doesn't allow 2 content types at the same time, so you will have to make 2 requests.

1. 
   [HttpPost("post.{format}"), FormatFilter]
   public int Post([FromBody]Employee employee)
   {
   // do yr work
   }
   http://localhost:1234/api/employees/Post.json
   http://localhost:1234/api/employees/Post.XML
