asp.net web api PUT method not supported - asp.net

Question

I am making a PUT request for a PersonController but it is not even reaching the controller. Instead I get following response from Server
{"message":"The requested resource does not support http method 'PUT'."}
But a get request GET /api/person is being served properly.
Here is the Person Controller
public class PersonController : ApiController
{
// GET: api/Person/5
[ResponseType(typeof(Person))]
public IHttpActionResult GetPerson(int id) {
//Served without any issues
}
// PUT: api/Person/5
[ResponseType(typeof(void))]
public IHttpActionResult PutPerson(int id, Person person) {
//Not reaching here!
}
}
Here is the PUT request as shown in fiddler
PUT http://localhost:xxxxx/api/person HTTP/1.1
Host: localhost:xxxxx
Connection: keep-alive
Content-Length: 38
Accept: application/json, text/javascript, */*; q=0.01

{"id":0,"name":"Person 11","age":"11"}
And the Server Response
HTTP/1.1 405 Method Not Allowed

{"message":"The requested resource does not support http method 'PUT'."}
Clearly, the PUT request is rejected by the IIS Express. What is the correct way to configure the IIS Express (VS 2013) to allow PUT and DELETE requests at the project level.
