Custom Resource Dictionary

Resource Dictionary Rules

Generally, we put some commonly used Color and Style into a theme.xaml.

This theme.xaml internally contains ResourceDictionary.

In normal projects, we would put it in App.xaml, but plugins don't have App.xaml, so this functionality is implemented in the AbstractPlugin class.

Example

Assuming in plugin ShadowViewer.Plugin.Bika (DLL name)

We have a file at /Themes/BikaTheme.xaml

Please implement the following accessor in your own plugin main class:

public override IEnumerable<string> ResourceDictionaries => new List<string>
{
    "ms-plugin://ShadowViewer.Plugin.Bika/Themes/BikaTheme.xaml"
};

This will automatically merge the resource dictionary into App.xaml when the plugin is loaded.

Note

If it's a built-in plugin, just use the ms-appx:/// path directly.

Development

The rest of the usage is consistent with regular WinUI projects.
