download file in offScreen browser

[Sergey Sahon]

I'm trying to download file in offScreen browser using cefSharp. My code is based on offscreen.example. JS opens new tab in browser which downloads file. I added new DownloadHelper:

public class DownloadHandler2 : IDownloadHandler

        {

            public void OnBeforeDownload(IBrowser browser, DownloadItem downloadItem, IBeforeDownloadCallback callback)

            {

                downloadItem.SuggestedFileName = @"c:\temp\temp.csv";

                if (!callback.IsDisposed)

                {

                    using (callback)

                    {

                        callback.Continue(downloadItem.SuggestedFileName, showDialog: false);

                    }

                }

            }

            public void OnDownloadUpdated(IBrowser browser, DownloadItem downloadItem, IDownloadItemCallback callback)

            {

                if (!downloadItem.IsInProgress && browser.IsPopup && !browser.HasDocument)

                {

                    browser.GetHost().CloseBrowser(false);

                }

                

            }

        }

the only problem that new blank Window is created. I do not want any windows created because this code will be part of server code.

if I add return false to ILifeSpanHandler.OnBeforePopup program download is not happening.

Is it possible to fix the issue with blank windows?
