Remarks

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.

Examples

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