WPF Screen Capture doesn't include title bar - wpf

Question

I implemented the code in the first answer to this question and it works great except that it doesn't include the title bar, which is a must for my needs. Does anybody have any idea what I'm doing wrong?
I've updated my example to show all the other commented out attempts that failed.
Here's my code:
Window shellView = Application.Current.MainWindow;
Rect bounds = VisualTreeHelper.GetDescendantBounds(shellView);
//Rect bounds = new Rect(new Size(shellView.ActualWidth, shellView.ActualHeight));
//Rect bounds = shellView.RestoreBounds;
//Rect bounds = VisualTreeHelper.GetContentBounds(shellView);
//Rect bounds = new Rect(new Size(VisualTreeHelperEx.FindDescendantByType<Window>(shellView).ActualWidth,
// VisualTreeHelperEx.FindDescendantByType<Window>(shellView).ActualHeight));
RenderTargetBitmap renderTarget = new RenderTargetBitmap((int)bounds.Width, (int)bounds.Height, 96, 96, PixelFormats.Pbgra32);
DrawingVisual visual = new DrawingVisual();
string fileName = $#"{Environment.GetFolderPath(Environment.SpecialFolder.Desktop)}\Screen_Capture.png";
if (_dialogService.ShowSaveFileDialog(ref fileName, "PNG Files | *.png"))
{
using (DrawingContext context = visual.RenderOpen())
{
VisualBrush visualBrush = new VisualBrush(shellView);
context.DrawRectangle(visualBrush, null, new Rect(new Point(), bounds.Size));
}
renderTarget.Render(visual);
PngBitmapEncoder bitmapEncoder = new PngBitmapEncoder();
bitmapEncoder.Frames.Add(BitmapFrame.Create(renderTarget));
using (Stream stm = File.Create(fileName))
{
bitmapEncoder.Save(stm);
}
}
And at XAMIMAX's request, what I can share of the XAML with names changed:

I hope that's enough of the XAML to help. I also tried the example at this link Generating a screenshot of a WPF window, but got the same results: no title bar.

Answer 1

Thanks to the link that #Clemens sent me to, I was able to use some of the code on that page to come up with this working method. It grabs a few pixels more that the active window, but that works for me!
private void TakeScreenshot()
{
var rect = new Rect();
GetWindowRect(GetForegroundWindow(), ref rect);
var bounds = new Rectangle(rect.Left, rect.Top, rect.Right - rect.Left, rect.Bottom - rect.Top);
var result = new Bitmap(bounds.Width, bounds.Height);
using (var graphics = Graphics.FromImage(result))
{
graphics.CopyFromScreen(new System.Drawing.Point(bounds.Left, bounds.Top), System.Drawing.Point.Empty, bounds.Size);
}
string fileName = $#"{Environment.GetFolderPath(Environment.SpecialFolder.Desktop)}\Screen_Capture.png";
if (_dialogService.ShowSaveFileDialog(ref fileName, "PNG Files | *.png"))
{
result.Save(fileName, ImageFormat.Png);
_dialogService.ShowInfoDialog(_localizationService["Shell.Views.Shell.HelpMenu.ScreenshotSaved"] + $"{fileName}");
}
}
