How to use IAsyncOperationWithProgress

AppInstallerAndProgress.cs

async Task InstallWithAppInstaller()
{
  var pm = new PackageManager();
  var volume = pm.GetDefaultPackageVolume();
                
  var operationWithProgress = pm.AddPackageByAppInstallerFileAsync(new Uri("https://<the app installer location>"),
                      AddPackageByAppInstallerOptions.None, volume);
                      
 
  operationWithProgress.Progress = ReportProgress;

  var result = await operationWithProgress;

   // NOTE: Sometimes you will see AsTask(progress) as an alternative.
   // I've found this won't work as expected: on many occasions the task never completes.
}

private void ReportProgress(IAsyncOperationWithProgress<DeploymentResult, DeploymentProgress> _, DeploymentProgress progress)
{
    Debug.WriteLine(progress.state + " " + progress.percentage + "%");
}
