        Collection<ResourceDictionary> applicationDictionaries = Application
            .Current
            .Resources
            .MergedDictionaries;

        if (applicationDictionaries.Count == 0)
        {
            return;
        }

        for (var i = 0; i < applicationDictionaries.Count; i++)
        {
            string sourceUri;

            if (applicationDictionaries[i]?.Source != null)
            {
                sourceUri = applicationDictionaries[i].Source.ToString().ToLower().Trim();

                if (sourceUri.Contains("pack://application:,,,/nodify;component"))
                {
                    switch (theme)
                    {
                        case ApplicationTheme.Dark:
                            applicationDictionaries[i] = new()
                            {
                                Source = new Uri("pack://application:,,,/Nodify;component/Themes/Dark.xaml",
                                    UriKind.Absolute)

Hi, I don't think this is a bug for nodify. Changing themes at runtime should be supported but it's up to you how you implement it.

You can check out the example apps (CTR+T to change the theme if there's no button for it in the UI). Last time I checked, I could change the theme just fine.

Make sure you unload the previous theme before loading the new theme.

You can try doing something similar to what I did here: https://github.com/miroiu/nodify/blob/master/Examples/Nodify.Shared/ThemeManager.cs

You can check out the example apps (CTR+T to change the theme if there's no button for it in the UI). Last time I checked, I could change the theme just fine.您可以查看示例应用程序（如果 UI 中没有按钮，则使用 CTR+T 更改主题）。上次我检查时，我可以很好地更改主题。

Make sure you unload the previous theme before loading the new theme.请确保在加载新主题之前卸载以前的主题。

You can try doing something similar to what I did here: https://github.com/miroiu/nodify/blob/master/Examples/Nodify.Shared/ThemeManager.cs您可以尝试执行类似于我在这里所做的操作：https://github.com/miroiu/nodify/blob/master/Examples/Nodify.Shared/ThemeManager.cs

I confirm that I have completed the complete switch because I directly modified the Url path of the old Theme resource dictionary. And the Node theme switch is successful, only the NodifyEditor background switch failed

Oh,I know the reason,I uesd

<nodify:NodifyEditor.Background>
        <StaticResource ResourceKey="SmallGridLinesDrawingBrush"/>
</nodify:NodifyEditor.Background>

thanks for your help
