What is the best way to stop a user from resizing the top-level window of an application written in WPF?

The WindowChrome class separates the functionality of the window frame from the visuals, and lets you control the boundary between the client and non-client areas of your application window. The WindowChrome class lets you put WPF content in the window frame by extending the client area to cover the non-client area.
First of all, create a new WPF project with the name WPFDialog. Drag one button and one textbox from the Toolbox. When the user clicks this button, it opens another dialog box with Yes, No, and Cancel buttons and displays a message “click any button” on it.
You will want to use the ResizeMode.NoResize on the window.
<Window x:Class="WpfApplication5.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" ResizeMode="NoResize"> </Window> A WPF quirk to note is that if ResizeMode="NoResize" and WindowStyle="None" you will lose the chrome around the entirely in Vista Aero.
