This package contains useful extensions for the WPF Window for .NET Framework and .NET 6.0+.
Extensions are provided as attached properties, accessible as winex:WindowEx.* via XAML:
| Property | Description |
|---|---|
| WindowShadow | Attaches a drop shadow to a window. |
| SystemMenu | Allows to adjust the window control box (mimimize, maximize and close buttons), icon (show/hide), and the system menu items. |
| Screen | Provides information about the display the window is currently on. Similar to the SystemParameters.PrimaryScreen* properties, but with multi-display support. |
You can download the Demo app to see these properties in action.
You can attach a drop shadow to a window without affecting the window template or content. The drop shadow is:
- Completely customizable (color, amount of blur, opacity, offset, corner radius, etc.)
- Transparent to mouse clicks (just like any standard window shadow)
- Does not affect the actual size of the host window
- Respects the "Show shadows under windows" option in Performance Options in Windows settings
- Style/ResourceDictionary-friendly and animatable
Before using this property, be sure to remove the default window shadow by setting
WindowStyle to None,
as well as any of the following:
- ResizeMode to
NoResize - AllowsTransparency to
True - WindowChrome.GlassFrameThickness to
0
Here's a minimal example:

Width="300" Height="200"
ResizeMode="NoResize"
WindowStartupLocation="CenterScreen"

<!-- Notice the new attached property below. -->
