Maui - Burn data to CdRome

I used this link :https://www.codeproject.com/Articles/24544/Burning-and-Erasing-CD-DVD-Blu-ray-Media-with-C-an and run this code passing argument the file to burn.

I have problem:

1. I await to task to download the file for my system. it give the path for the file also.
2. Later I run the Process the exe above with the file path that i download in step 1.
3. I want the process info will run only after the task finished.
4. They run parallels(1&2) i want Sequently(1 and later 2).

5.How I share the file path that create in step 1 to step 2?

Its works only if the file path is hardcoded? not sharing.

Could you supply sniped code?

Its works only if the file path is hardcoded.

I download filed from our site.

//Create the file from stream in destination
                                 var fileStream = File.Create(zipPathForFolderOrPathForFile);
                                 contentStream.CopyTo(fileStream);
                                 fileStream.Dispose();
                                 contentStream.Dispose();

keep local copy in disk and run process.

  string fileArgument = zipPathForFolderOrPathForFile; // problematic row
                             await using var stream = await FileSystem.OpenAppPackageFileAsync("externalApplications.xml");
                             var serializer = new System.Xml.Serialization.XmlSerializer(typeof(ExternalAppsXmlData));
                             var result = (ExternalAppsXmlData)serializer.Deserialize(stream);
                             var fileToExecutePath = result.ExternalApps?[1].FullPath;

                             if (System.IO.File.Exists(fileToExecutePath))
                             {
                                 ProcessStartInfo psi = new ProcessStartInfo(fileToExecutePath);
                                 psi.UseShellExecute = false;
                                 psi.CreateNoWindow = true;
                                 psi.Arguments = fileArgument;

                                 using (Process proc = Process.Start(psi))
                                 {
                                     proc.WaitForExit();
                                     var exitCode = proc.ExitCode;
                                     if (exitCode == 0)
                                     {
                                         if (File.Exists(fileArgument))
                                         {
                                             File.Delete(fileArgument);
                                         }
                                         MainThread.BeginInvokeOnMainThread(async () =>
                                         {
                                             await Application.Current.MainPage.Navigation.PushAsync(new MainPage("DownloadView"), true);
                                         });
                                     }
                                 };

                             }
                             else
                             {
                                 _logger.Error("There is no executable to run.");
                             }

The path from config was incorrect.

Now it works:)
