# wpf-xaml-style-generator

Generate XAML styles, control templates, and resource dictionaries with theme support for WPF applications. This skill creates consistent, maintainable UI styling following modern design principles.

## Capabilities

- Generate control styles and templates
- Create resource dictionaries with theme support
- Set up light/dark theme switching
- Generate brush and color resources
- Create custom control templates
- Set up implicit vs explicit styles
- Generate animation resources
- Configure Fluent Design integration

### Theme Manager

```csharp
public class ThemeManager
{
    private const string ThemesPath = "pack://application:,,,/Resources/Themes/";

    public static void SetTheme(string themeName)
    {
        var app = Application.Current;
        var dictionaries = app.Resources.MergedDictionaries;

        // Remove existing theme
        var existingTheme = dictionaries.FirstOrDefault(d =>
            d.Source?.OriginalString.Contains("Colors.") ?? false);

        if (existingTheme != null)
        {
            dictionaries.Remove(existingTheme);
        }

        // Add new theme
        var themeUri = new Uri($"{ThemesPath}Colors.{themeName}.xaml");
        dictionaries.Insert(0, new ResourceDictionary { Source = themeUri });
    }

    public static string CurrentTheme { get; private set; } = "Light";

    public static void ToggleTheme()
    {
        CurrentTheme = CurrentTheme == "Light" ? "Dark" : "Light";
        SetTheme(CurrentTheme);
    }
}
```

### App.xaml

```xml
<Application x:Class="MyApp.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <!-- Theme colors (first so brushes can reference them) -->
                <ResourceDictionary Source="Resources/Themes/Colors.Light.xaml"/>

                <!-- Brushes -->
                <ResourceDictionary Source="Resources/Brushes.xaml"/>

                <!-- Control Styles -->
                <ResourceDictionary Source="Resources/Styles/ButtonStyles.xaml"/>
                <ResourceDictionary Source="Resources/Styles/TextBoxStyles.xaml"/>
                <ResourceDictionary Source="Resources/Styles/ComboBoxStyles.xaml"/>
                <ResourceDictionary Source="Resources/Styles/DataGridStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>
```

## Best Practices

1. **Use DynamicResource**: For theme-switchable resources
2. **Organize by function**: Colors, brushes, styles separately
3. **Follow naming conventions**: Consistent resource key names
4. **Provide base styles**: Allow easy customization
5. **Test all themes**: Verify contrast and accessibility
6. **Document resources**: Comment complex templates
