Why does my console app not have an icon when started with Process.Start()?

I've got an app that downloads an .exe to a temporary folder and runs it with the System.Diagnostics.Process class. So far I've run two different apps with it. One is a console app, the other is a full windows app. The windows app has its icon in the taskbar/titlebar, but the console app only has a generic application icon. If I navigate to the temp folder the console app does have its icon; and running it "by hand" (double-clicking in explorer) also gives it the correct icon.

What could be the cause of this?

Additional info: The ProcessStartInfo class does not offer any flags concerning the icon. I'm running the process with UseShellExecute=true and ErrorDialog=true. Also, the windows app is started maximized but the console app is minimized (as specified by the WindowStyle member of ProcessStartInfo). Finally, the icon for the console app only includes a 32x32x4bpp icon, while the windows app has a large selection of different formats.

Added: I gave the downloaded app a proper icon. Still no go. :(

Added 2: Oh, right, Windows 7 x64.

Update: Just tried some more experiments. I created a new C++ (unmanaged, not .NET) application with just "press any key to continue" in it and gave it an icon. The icon shows up normally in explorer, and when I run it from explorer, the icon is in the window title bar.

However, when I start the application from Visual studio (via F5 or Ctrl-F5); or when I run the application via another .NET application and Process.Start() - the icon doesn't appear. Why?

I'm not sure why this happens, but a work-around is to set the WorkingDirectory in the ProcessStartInfo structure to the directory of the EXE.

This works whether UseShellExecute is true or not.

This code shows console application with user defined icon normally:

        Process p = new Process();

        p.StartInfo = new ProcessStartInfo("ConsoleApplication1.exe")
            {
                UseShellExecute = true,
                ErrorDialog = true,
                WindowStyle = ProcessWindowStyle.Minimized
            };

        p.Start();

Icon file used in my ConsoleApplication1.exe includes all resolutions.

Therefore I think problem source may be in:

  1. There isn't correct resolution image in ico-file (But why when you start it manually app looks normally on tray?)
  2. Security permissions

I suppose that downloadable app previously didnt have an icon. But now is has, so may be the windows has buffered icon and you just need to reboot. Im not sure. I just tryed to run one console app from another and icons has displayed. But when I changed icon and recompile applications I saw old icon until I have reboot. So its obviously windows problem
