How to enable dark system menu in WPF

Question

Answer 1

Hi,@ quan zhao. Welcome to Microsoft Q&A. To enable the dark system menu with move, minimize, and maximize options in a WPF application, you could use the same Windows API functions. Here's how you can do it.

You can call the EnableDarkSystemMenu method in the constructor of your MainWindow or at any appropriate place in your application where you want to enable the dark system menu.

  [DllImport("uxtheme.dll", EntryPoint = "#135", SetLastError = true, CharSet = CharSet.Unicode)]

  private static extern int SetPreferredAppMode(int preferredAppMode);

  [DllImport("uxtheme.dll", EntryPoint = "#136", SetLastError = true, CharSet = CharSet.Unicode)]

  private static extern void FlushMenuThemes();

  public MainWindow()

  {

      InitializeComponent();

      EnableDarkSystemMenu();

  }

  private void EnableDarkSystemMenu()

  {

      SetPreferredAppMode(2); // Enable dark system menu

      FlushMenuThemes();

  }
