DisableDpiAwarenessAttribute Class

Allows WPF applications to disable dots per inch (dpi) awareness for all user interface elements.

Namespace:  System.Windows.Media
Assembly:  WindowsBase (in WindowsBase.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false)]
public sealed class DisableDpiAwarenessAttribute : Attribute
<DisableDpiAwarenessAttribute .../>

By default, WPF applications are dpi aware, which affects how user interface layout is calculated. However, an application can disable dpi awareness by adding the DisableDpiAwarenessAttribute to the application assembly.

Caution noteCaution:

It is not recommended that you set this attribute for your application, unless you need all user interface elements of your application to be non-dpi aware.

The following example shows how to disable Dpi awareness for the WPF application by declaring DisableDpiAwarenessAttribute at the assembly level.

// Disable Dpi awareness in the application assembly.
[assembly: System.Windows.Media.DisableDpiAwareness]

System.Object
  System.Attribute
    System.Windows.Media.DisableDpiAwarenessAttribute
