为什么Windows 7不能加载PresentationFramework.Aero2程序集?

我最近完成了我使用Windows 8开发的第一个WPF应用程序。它在我的机器上运行良好。 我的一个朋友也在他的Windows 8机器上的视觉工作室中运行,而且工作。 我在我的机器上点击一次安装程序,安装正常并运行。

我在虚拟机上安装了Windows 7,并尝试使用点击一次来安装它。 它提取了.NET 4.5和SQL Server Compact,安装过程看起来完美无瑕。 当Windows 7试图运行该应用程序时,没有发生任何有用的事情。 我在virtualbox中安装了Visual Studio,并能够获得这个堆栈跟踪。

我在Google上查找了PresentationFramework.Aero2,遇到了3个SO问题和1个MSDN问题。 MSDN的问题给了我一个我认为可能的暗示。 如果我去C:\ Windows \ Microsoft.NET \ Framework \ 4.0 \ WPF没有PresentationFramework.Aero2.dll文件,而在Windows 8上有…所以我复制并粘贴到Windows 7的相当地方希望实现一些东西,但没有什么结果。

这里是堆栈跟踪:

我遇到了类似的问题。 上下文:在Windows 8上使用Visual Studio 2012,Blend for 2012,.NET 4.5开发WPF应用程序。 APP.XAML引用了PresentationFramework.Aero2的主题。 使用ClickOnce分发应用程序。

在Windows 8上,没有问题。 在Windows XP / Vista / 7上,应用程序会在上面记录的“无法加载程序集”异常的情况下(在引用Aero2的第一个子页面上)部分崩溃。

尝试修复:标记Aero2复制本地项目(没有帮助),试图包含在ClickOnce安装程序(没有出现在可用程序集列表中),复制到目标Windows7机器下的WPF文件夹下的c:\ windows \ microsoft.net \ framework \ v4.xx \ wpf(没有帮助)。

解析度:

将项目中的引用从PresentationFramework.Aero2替换为PresentationFramework.Aero,然后修改匹配的XAML引用。 可以随时推送到非Windows 8的机器,并运行。 开发工作正常。 只有差别发现进度条的默认外观是光泽/ 3d。
