FileLabels no son visibles - c #, sharpdx

Intento capturar capturas de pantalla de escritorio utilizando SharpDX. Mi aplicación es capaz de capturar capturas de pantalla pero sin etiquetas en el Explorador de Windows. Probé 2 soluciones pero sin cambio. Intenté encontrar en la documentación cualquier información, pero sin cambios.

Aquí está mi código:

        public void SCR()
{
uint numAdapter = 0; // # of graphics card adapter
uint numOutput = 0; // # of output device (i.e. monitor)

// create device and factory

var device = new SharpDX.Direct3D11.Device(SharpDX.Direct3D.DriverType.Hardware);
var factory = new Factory1();

// creating CPU-accessible texture resource
var texdes = new SharpDX.Direct3D11.Texture2DDescription
{
CpuAccessFlags = SharpDX.Direct3D11.CpuAccessFlags.Read,
BindFlags = SharpDX.Direct3D11.BindFlags.None,
Format = Format.B8G8R8A8_UNorm,
Height = factory.Adapters1[numAdapter].Outputs[numOutput].Description.DesktopBounds.Height,
Width = factory.Adapters1[numAdapter].Outputs[numOutput].Description.DesktopBounds.Width,
OptionFlags = SharpDX.Direct3D11.ResourceOptionFlags.None,
MipLevels = 1,
ArraySize = 1
};
texdes.SampleDescription.Count = 1;
texdes.SampleDescription.Quality = 0;
texdes.Usage = SharpDX.Direct3D11.ResourceUsage.Staging;
var screenTexture = new SharpDX.Direct3D11.Texture2D(device, texdes);

// duplicate output stuff
var output = new Output1(factory.Adapters1[numAdapter].Outputs[numOutput].NativePointer);
var duplicatedOutput = output.DuplicateOutput(device);
SharpDX.DXGI.Resource screenResource = null;
SharpDX.DataStream dataStream;
Surface screenSurface;
var i = 0;

var miliseconds = 2500000;
while (true)
{
i++;
// try to get duplicated frame within given time
try
{
SharpDX.DXGI.OutputDuplicateFrameInformation duplicateFrameInformation;
duplicatedOutput.AcquireNextFrame(miliseconds, out duplicateFrameInformation, out screenResource);
}
catch (SharpDX.SharpDXException e)
{
if (e.ResultCode.Code == SharpDX.DXGI.ResultCode.WaitTimeout.Result.Code)
{
// this has not been a successful capture
// thanks @Randy

// keep retrying
continue;
}
else
{
throw e;
}
}

device.ImmediateContext.CopyResource(screenResource.QueryInterface<SharpDX.Direct3D11.Resource>(), screenTexture);
screenSurface = screenTexture.QueryInterface<Surface>();


//  screenSurface.Map(SharpDX.DXGI.MapFlags.Read, out dataStream);

int width = output.Description.DesktopBounds.Width;
int height = output.Description.DesktopBounds.Height;
var boundsRect = new System.Drawing.Rectangle(0, 0, width, height);
var mapSource = device.ImmediateContext.MapSubresource(screenTexture, 0, MapMode.Read, SharpDX.Direct3D11.MapFlags.None);
using (var bitmap = new System.Drawing.Bitmap(width, height, PixelFormat.Format32bppArgb))
{
// Copy pixels from screen capture Texture to GDI bitmap
var bitmapData = bitmap.LockBits(boundsRect, ImageLockMode.WriteOnly, bitmap.PixelFormat);
var sourcePtr = mapSource.DataPointer;
var destinationPtr = bitmapData.Scan0;
for (int y = 0; y < height; y++)
{
// Copy a single line
Utilities.CopyMemory(destinationPtr, sourcePtr, width * 4);

// Advance pointers
sourcePtr = IntPtr.Add(sourcePtr, mapSource.RowPitch);
destinationPtr = IntPtr.Add(destinationPtr, bitmapData.Stride);
}

// Release source and dest locks
bitmap.UnlockBits(bitmapData);

device.ImmediateContext.UnmapSubresource(screenTexture, 0);

bitmap.Save(string.Format(@"d:scr{0}.png", i));
}


//  var image = FromByte(ToByte(dataStream));

//var image = getImageFromDXStream(1920, 1200, dataStream);
//image.Save(string.Format(@"d:scr{0}.png", i));

// dataStream.Close();
//screenSurface.Unmap();
screenSurface.Dispose();
screenResource.Dispose();
duplicatedOutput.ReleaseFrame();
}
}
