ASP.NET MVC 4 Web Api ajax file upload
===

I am developing some sort of service using asp.net mvc 4 web api. On one form user must upload few files and then submit form to server. Problem is in ajax file upload to asp.net mvc web api. I have already implemented upload without ajax. But i need it's done with ajax.
This is implementation of 

    public Task<HttpResponseMessage> PostJob()
    {
        if (!Request.Content.IsMimeMultipartContent())
        {
            throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.UnsupportedMediaType));
        }

        string path = HttpContext.Current.Server.MapPath(string.Format("~/Resources/Documents"));
        MultipartFormDataStreamProvider provider = new MultipartFormDataStreamProvider(path);
        var request = Request.Content.ReadAsMultipartAsync(provider);

        var task = request.ContinueWith<HttpResponseMessage>(t =>
        {
            if (t.IsFaulted || t.IsCanceled)
            {
                return new HttpResponseMessage(HttpStatusCode.InternalServerError);
            }

            string fileName = provider.BodyPartFileNames.FirstOrDefault().Value;
            string originalName = provider.BodyPartFileNames.FirstOrDefault().Key.TrimStart('"').TrimEnd('"');
            string RandomName = provider.BodyPartFileNames.First().Value + Path.GetExtension(originalName);

            FileInfo file = new FileInfo(fileName);
            file.CopyTo(Path.Combine(path, originalName), true);
            file.Delete();


            return new HttpResponseMessage(HttpStatusCode.Created);

        });

I have found article that does this using HTML5 http://www.strathweb.com/2012/04/html5-drag-and-drop-asynchronous-multi-file-upload-with-asp-net-webapi/. I need this work in IE8. Maybe you have any ideas?


Any help is appreciated,
