c# - 为什么 Windows 7 无法加载程序集 PresentationFramework.Aero2？

Question

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 friend 也在他的 Windows 8 机器上的 visual studio 中运行了它，并且成功了。我在我的机器上使用单击一次安装程序，它安装正常并运行。

我在 Virtual Box 上安装了 Windows 7，并尝试单击一次进行安装。它获取了 .NET 4.5 和 SQL Server Compact，安装过程似乎完美无缺。当 Windows 7 尝试运行该应用程序时，没有发生任何有用的事情。我在 virtualbox 中安装了 Visual Studio，并且能够获取此堆栈跟踪。

我在 Google 上查找了 PresentationFramework.Aero2，发现了 3 个 SO 问题和一个 MSDN 问题。 MSDN 问题给了我一个暗示，我认为它可能是什么。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...所以我将它复制并粘贴到 Windows 7 等效的地方希望想要有所成就，却一无所获。

这是堆栈跟踪:

Answer 1

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

在 Windows 8 上，没有问题。在 Windows XP/Vista/7 上，应用程序会在执行过程中崩溃(在引用 Aero2 的第一个子页面上)，并记录上述“无法加载程序集”异常。

尝试修复:标记 Aero2 以在项目中复制本地(没有帮助)，尝试包含在 ClickOnce 安装程序中(未出现在可用程序集列表中)，复制到目标 Windows7 机器上的 WPF 文件夹中 c:\windows\microsoft.net\framework\v4.xx\wpf(没有帮助)。

解决方案:

将项目中的引用从 PresentationFramework.Aero2 替换为 PresentationFramework.Aero，然后修改 XAML 引用以匹配。可以很容易地推送到非 Windows 8 机器并让它运行。开发工作正常。唯一发现的区别是进度条的默认外观是有光泽的/3d。
