Web service proxy gen for Windows Store Applications

Question

Hi,

I am generating the C# web service proxies from a WSDL using the service reference in Visual Studio Premium 2013. This is for a Windows Store application. The services get generated fine and I set the cookie(per snippet below). The issue is that the request doesnt seeem to be able to pick up the cookie(but the payload goes through). Are the proxies being generated using .NET instead of WinRT libraries ? 

Windows.Web.Http.Filters.HttpBaseProtocolFilter filter = new Windows.Web.Http.Filters.HttpBaseProtocolFilter();
            
                filter.AllowAutoRedirect = false;
                
                filter.CookieManager.SetCookie(new Windows.Web.Http.HttpCookie("cookieName", "myDomain", "/")
                {
                    HttpOnly = true,
                    Value = "xcookievalue"                
                });
