C# WPF Material DesignThemes 5.0 命名规则改变后导致找不到资源

复制代码

	MaterialDesignInXAML库从5.0.0版本开始的命名规则变化，使用新的ResourceDictionary时遇到的themes/materialdesigntheme.defaults.xaml找不到.

原本在App.xaml中定义如下：

<ResourceDictionary.MergedDictionaries>

复制代码

<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />

<ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />

<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />

<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />

</ResourceDictionary.MergedDictionaries>

自5.0.0版本更新后，命名方式改变，两条引用找不到。

复制代码

	Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml"

Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml"

这两条改为：

复制代码

	Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesign3.Defaults.xaml"

	Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Secondary/MaterialDesignColor.Lime.xaml"

最终整个Application.ResourcessourceDictionary>

复制代码

    <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
