Setting DPI Awareness of a new Process to display tiff

问题

I want to display a tiff file using photoviewer.

    private void StartProcessWithoutShell(string filePath)
    {
        string path = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles);
        photoViewer.StartInfo = new ProcessStartInfo("rundll32.exe",
                  String.Format("\"{0}{1}\", ImageView_Fullscreen {2}",
                  Environment.Is64BitOperatingSystem ? path.Replace(" (x86)", "") : path,
                  @"\Windows Photo Viewer\PhotoViewer.dll",
                  filePath));
        photoViewer.StartInfo.UseShellExecute = false;
        photoViewer.Start();
    }

Problem is that the image is blurry.When i open the file via double click it looks just fine. My guess is that i have to set the SetProcessDpiAwarenessContext to unaware but i do not know how in c#. I had another approach where i use ShellExecute, but there i am unable to kill the process because it retruns no processId.

Edit photoviewer is a process

photoViewer = new Process();
