我的WPF项目使用.NET 4客户端配置文件。当我添加
<ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" />
到<Application.Resources>我在调试模式下启动程序时遇到此异常（在发布模式下程序无声地崩溃）：
类型的第一次机会异常 'System.Windows.Markup.XamlParseException'发生在 PresentationFramework.dll
其他信息：'设置属性 'System.Windows.ResourceDictionary.Source'引发了异常。线 数字'14'和行位置'14'。
当我将PresentationFramework.Aero的属性“Copy Local”设置为true时，一切正常，异常就消失了。
“Copy Local”会在我的输出目录中放置PresentationFramework.Aero的副本，因此我需要将它包含在我的安装项目中。 为什么这有必要？根据MSDN PresentationFramework.aero包含在.NET framework 4.0客户端配置文件中，因此也包含在GAC中。我觉得在我的应用程序中部署框架文件感觉不舒服。
UDATE：
正如Hans Passant建议我验证目录PresentationFramework.Aero存在于C:\windows\microsoft.net\assembly\gac_msil中。然后我使用fuslogvw.exe生成以下日志，在启动我的应用程序“SetACL Studio.exe”时创建，而ApplicationFramework.Aero.dll不在应用程序目录中。有趣的是，加载程序甚至不检查GAC 。为什么呢？

更新2：
这是gacutil的输出：

我刚在MSDN找到了以下内容：
您还可以通过提供对程序集的动态引用 调用方法只包含有关程序集的部分信息 仅指定程序集名称。在这种情况下，只有 在应用程序目录中搜索程序集，而不是其他目录 检查发生。
这解释了我看到的行为以及为什么GAC没有搜索PresentationFramework.aero.dll。我将动态引用更改为完整引用，并从PresentationFramework.aero中删除了“Copy Local”。它现在可以在我的应用程序目录中使用PresentationFramework.aero.dll。
供参考，这是工作资源字典代码：
<ResourceDictionary Source="/PresentationFramework.Aero,Version=3.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35,processorArchitecture=MSIL;component/themes/Aero.NormalColor.xaml" />
简而言之，删除主题的本地副本（如果已在解决方案中添加），请在Application.Resources（资源字典）下的App.xaml文件中添加完整引用，这应该可以。
