WebApi with Odata NextPage and Count not appearing in the JSON response

Question

I have a webapi method that I want to switch oData paging etc on. I followed the example in http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/supporting-odata-query-options

My method looks like:

public PageResult<UserViewModel> GetUsers(ODataQueryOptions<UserViewModel> options)
{
    var settings = new ODataQuerySettings()
    {
        PageSize = 2
    };

    var results = UserLogic.GetUsers(userId, UserManager, _db);
    var filtered = options.ApplyTo(results, settings);

    var pagedResult = new PageResult<UserViewModel>(
        filtered as IEnumerable<UserViewModel>,
        Request.GetNextPageLink(),
        Request.GetInlineCount());
    return pagedResult;
}  

That the count is populated and the next page link is there and the correct oData options are applied i.e. sort order etc. When I return it in my api method, the correct data comes back, but the count and next link don't appear in my json.

Am I missing a setting to turn this on?

i.e. this is my json response:

This should work.

Be sure to remove the [EnableQuery] attribute if it is being applied to your method or controller. This will cause the returned JSON to not include the count and next link.
