adding Response to user in mcv4 web-api

Question

I need in MCV4 web-api to return a http status to user (after calling POST/GET methods).

(New project of MCV4, and choose: WEB-API).

I have VS 2010, and I looked at the sample on Returning http status code from Web Api controller , but it didn't work for me.

I am using ApiController to handle GET/POST methods.

For following code:

[ResponseType(typeof(User))]
public HttpResponseMessage GetUser(HttpRequestMessage request, int userId, DateTime lastModifiedAtClient)
{
    var user = new DataEntities().Users.First(p => p.Id == userId);
    if (user.LastModified <= lastModifiedAtClient)
    {
         return new HttpResponseMessage(HttpStatusCode.NotModified);
    }
    return request.CreateResponse(HttpStatusCode.OK, user);
}

I put the above in class of type: apicontroller - ResponseType is unknown, and indeed, in code, I added:

using System.Web.Http;

But, still ResponseType is unknown.

I am using 32bit for my win-api.

How can I return status to user (whether it is error, or OK).

Thanks :)

As per MSDN document, the ResponseTypeAttribute is in the namespace "System.Web.Http.Description"

Refer: ResponseTypeAttribute
