Hi Mohsin,
Void
Any Entity/Datatype
HttpResponseMessage - When Web API return type is HttpResponseMessage, Web API converts the return value directly into an HTTP response message.
IHttpActionResult - HttpActionResult is introduced in Web API 2, IHttpActionResult interface acts like a factory for HttpResponseMessage.

A Web API controller action can return any of the following:
1. void
2. HttpResponseMessage
3. IHttpActionResult
4. Some other type
Depending on which of these is returned, Web API uses a different mechanism to create the HTTP response.
