Upload a new media item from code in v8

I am trying to download a file and then upload it to the media section. It worked with v7.

But I am not sure on how to fix this in v8.

// add media item var newmedia = _mediaService.CreateMediaWithIdentity(photo.Title, -1, "image"); var destinationFolder = HostingEnvironment.MapPath("~/App_Data/FlickrTemp/"); System.IO.Directory.CreateDirectory(destinationFolder); var newFileName = Path.Combine(destinationFolder, photo.PhotoId + ".jpg"); // download the file new WebClient().DownloadFile(photo.LargeUrl, newFileName); var s = new FileStream(newFileName, FileMode.Open); // next line won't compile newmedia.SetValue("umbracoFile", Path.GetFileName(newFileName), s); // PLEASE HELP :-) s.Close(); _mediaService.Save(newmedia);

I need a ContentTypeBaseServiceProvider. I don't know what it is and how to get it...
