How to remove the icon of a WPF window
Unfortumately WPF does not provide any function to remove the icon of a window. One solution could be setting the icon to a transparent icon. But this way the extra space between the window border and title remains.
The better approach is to use a function provided by the Win32 API to remove the icon.
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
protected override void OnSourceInitialized(EventArgs e)
{
IconHelper.RemoveIcon(this);
}
}
public static class IconHelper
{
[DllImport("user32.dll")]
static extern int GetWindowLong(IntPtr hwnd, int index);
[DllImport("user32.dll")]
static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle);
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,
int x, int y, int width, int height, uint flags);
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hwnd, uint msg,
IntPtr wParam, IntPtr lParam);
const int GWL_EXSTYLE = -20;
const int WS_EX_DLGMODALFRAME = 0x0001;
const int SWP_NOSIZE = 0x0001;
const int SWP_NOMOVE = 0x0002;
const int SWP_NOZORDER = 0x0004;
const int SWP_FRAMECHANGED = 0x0020;
const uint WM_SETICON = 0x0080;
public static void RemoveIcon(Window window)
{
// Get this window's handle
IntPtr hwnd = new WindowInteropHelper(window).Handle;
// Change the extended window style to not show a window icon
int extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_DLGMODALFRAME);
// Update the window's non-client area to reflect the changes
SetWindowPos(hwnd, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE |
SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);
}
}

This was a good article. I hat going into the Win32 stuff so having a class like this means I can add to any future projects that require this functionality.
Thanks

I was trying to do this on XP Professional and it did not appear to work. Maybe I am missing something (I do that on occasion).
I still get the default windows icon on my window but no longer get the context menu (that shows Restore, Move, Size, Minimize, etc). I basically copied the code from here and used it in my application. Nothing was changed and I double checked that I did not get a copy/paste error.

SendMessage(hwnd, WM_SETICON, IntPtr.Zero, IntPtr.Zero) can remove the Icon from XP

Another way to do it:
<Window x:Class="Transparent.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Icon="transparent.png"
Title="Window1" SizeToContent="WidthAndHeight">

The SendMessage solution does not remove the icon in VisualStudio 2010 in XP.

The "transparent.png" approach does not remove the space reserved for the icon even thought there is no icon showing.

SetWindowLong by itself doesn't work on Vista x64 (VS2010) on remote desktop.
Requires both SetWindowLong and SendMessage.

re: WindowStyle="ToolWindow"
Yes, that will remove the icon, but it also changes the style of the buttons in the caption bar.
