Per-Monitor Aware WPF Sample\>
==============================

This sample demonstrates updating a Windows Presentation Foundation (WPF) application to be per-monitor DPI-aware.

The sample consists of two projects:

-   **NativeHelpers.vcxproj** The native helper project that implements the core functionality to make a WPF application per-monitor DPI-aware
-   **WPFApplication.csproj** A sample WPF application that inherits from the PerMonitorDPIWindow base class and showcases how the application window resizes when the user moves the window to another monitor with a different DPI or when the user changes the DPI by adjusting the Display slider in Control Panel.
