How to use?

First, your application needs to load custom styles, add in the MyApp\App.xaml file:

<Application
  ...
  xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml">
  <Application.Resources>
    <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
        <ui:ThemesDictionary Theme="Light" />
        <ui:ControlsDictionary />
      </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
  </Application.Resources>
</Application>

If your application does not have MyApp\App.xaml file, use ApplicationThemeManager.Apply(frameworkElement) to apply/update the theme resource in the frameworkElement.

public partial class MainWindow
{
    public MainWindow()
    {
        InitializeComponent();
        ApplicationThemeManager.Apply(this);
    }
}

Now you can create fantastic apps, e.g. with one button:

<ui:FluentWindow
  ...
  xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml">
  <StackPanel>
      <ui:TitleBar Title="WPF UI"/>
      <ui:Card Margin="8">
          <ui:Button Content="Hello World" Icon="{ui:SymbolIcon Fluent24}" />
      </ui:Card>
  </StackPanel>
</ui:FluentWindow>

Microsoft Property

Design of the interface, choice of colors and the appearance of the controls were inspired by projects made by Microsoft for Windows 11.
The Wpf.Ui.Gallery app includes icons from Microsoft WinUI 3 Gallery app. They are used here as an example of creating tools for Microsoft systems.

Segoe Fluent Icons

WPF UI uses Fluent System Icons. Although this font was also created by Microsoft, it does not contain all the icons for Windows 11. If you need the missing icons, add Segoe Fluent Icons to your application.
According to the EULA of Segoe Fluent Icons we cannot ship a copy of it with this dll. Segoe Fluent Icons is installed by default on Windows 11, but if you want these icons in an application for Windows 10 and below, you must manually add the font to your application's resources.
https://docs.microsoft.com/en-us/windows/apps/design/style/segoe-fluent-icons-font
https://docs.microsoft.com/en-us/windows/apps/design/downloads/#fonts

In the app dictionaries, you can add an alternate path to the font

<FontFamily x:Key="SegoeFluentIcons">pack://application:,,,/;component/Fonts/#Segoe Fluent Icons</FontFamily>
