Visual Studio 2022中WPF多项目StaticResource无法解析问题求助

我使用Visual Studio 2022开发基于.NET Framework 4.8的WPF解决方案，方案包含两个项目：作为应用入口的Startup项目，以及存放Resource Dictionary和App.xaml的Views项目。当在控件中使用Resource Dictionary中的项（如样式、字体）作为StaticResource时，出现「无法解析资源」的错误。

App.xaml 代码 #

<Application x:Class="Views.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             Startup="OnStartup">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Styles/Colors.xaml"/>
                <ResourceDictionary Source="Styles/Fonts.xaml"/>
                <ResourceDictionary Source="Styles/Global.xaml"/>
                <ResourceDictionary Source="Styles/Windows.xaml"/>
                <ResourceDictionary Source="Styles/Buttons.xaml"/>
                <ResourceDictionary Source="Styles/Storyboards.xaml"/>
                <ResourceDictionary Source="Styles/ScrollBar.xaml"/>
                <ResourceDictionary Source="Styles/Images.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

Fonts.xaml 代码 #

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <FontFamily x:Key="MulishRegular">pack://application:,,,/Views;component/Resources/Fonts/Mulish-Regular.ttf#Mulish</FontFamily>
    <FontFamily x:Key="MulishLight">pack://application:,,,/Views;component/Resources/Fonts/Mulish-Light.ttf#Mulish Light</FontFamily>
    <FontFamily x:Key="MulishMedium">pack://application:,,,/Views;component/Resources/Fonts/Mulish-Medium.ttf#Mulish Medium</FontFamily>
    <FontFamily x:Key="MulishBold">pack://application:,,,/Views;component/Resources/Fonts/Mulish-Bold.ttf#Mulish Bold</FontFamily>
</ResourceDictionary>

错误情况 #

使用StaticResource引用资源（如MulishRegular）时，提示：

无法解析资源'MulishRegular'

已尝试的无效操作 #

• 重新下载项目
• 清理.vs文件夹

临时解决方法 #

将资源文件从单独的Views项目移至Startup项目的根目录下，问题暂时解决。
