What is the difference between HttpResponseMessage and HttpResponseException

Question

I tried to understand both and write sample code:

 public HttpResponseMessage Get()
 {
     var response = ControllerContext.Request
                                 


        

Answer 1

HttpResponseException is useful when your Controller Action signature looks like

  Foo Get(int id)

In this case, you cannot easily return status code like 400.

Be aware that HttpResponseMessage is going away in the next release of Web API.
