我最近完成了我使用Windows 8開發的第一個WPF應用程序。它在我的機器上運行良好。我的一位朋友也在他的Windows 8機器上的視覺工作室中運行它，並且工作正常。我在我的機器上點擊一次安裝程序，安裝正常並運行。爲什麼Windows 7無法加載AssemblyFramework.Aero2？
我在虛擬盒子上安裝了Windows 7，並嘗試使用點擊一次來安裝它。它提取了.NET 4.5和SQL Server Compact，安裝過程看起來完美無瑕。當Windows 7試圖運行該應用程序時，沒有發生任何有用的事情。我在virtualbox中安裝了Visual Studio，並能夠獲取此堆棧跟蹤。
我在Google上查找了PresentationFramework.Aero2，並遇到了3個SO問題和1個MSDN問題。 MSDN的問題給了我一些我認爲可能的暗示。如果我到C：\ Windows \ Microsoft.NET \ Framework \ 4.0 \ WPF沒有PresentationFramework.Aero2.dll文件，而在Windows 8上有...所以我複製並粘貼到Windows 7等效位置希望實現某些東西，但沒有任何結果。
這裏是堆棧跟蹤：

哦，這也稱爲向後兼容性？我不知道這個！ –
@PaulVilevac，你是什麼意思「替換引用...到PresentationFramework.Aero」？你究竟如何「替換」？您是否使用過.Aero，或者您的解決方案是否保留了非Windows8設備上的Aero2樣式？ –
對於其他人感到困惑的是，您只需從項目中移除'PresentationFramework.Aero2'引用並添加'PresentationFramework.Aero'引用。此外，您還需要在所有名稱空間導入中將** Aero2 **更改爲** Aero **;例如'的xmlns：主題= 「CLR-名稱空間：Microsoft.Windows.Themes;裝配= PresentationFramework.Aero」'。事情已經爲我解決了。 – dotNET
