BackgroundUploader for Xamarin.Forms C#

Hi Experts,
I am working on converting my WindowsPhone project to Xamarin.Forms project.
I had a BackgroundUploader task for uploading my video files to server in background. However, I am not able to find a similar class in Xamarin Forms that does the same job.
Below is my BackgroundUploader code for WindowsPhone project.
Any kind suggestions please.

    BackgroundUploader bguploader = new BackgroundUploader();
    bguploader.SetRequestHeader(RequestHeader, jsonConverter.Serialize(Video));

    UploadOperation upload = bguploader.CreateUpload(new Uri(url), videoFile);
    Progress<UploadOperation> callback = new Progress<UploadOperation>(UploadProgress);
    await upload.StartAsync().AsTask(canceltoken.Token, callback);
