开发了一个gui工具，有同事在win7环境下发现界面无法加载出来。
经过调试发现，在view初始化的过程中，提示PresentationFramework.Aero2无法加载，异常信息如下：
{System.BadImageFormatException: Could not load file or assembly 'PresentationFramework.Aero2, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)

查看自己的代码，确实在窗体中使用了主题库
xmlns:Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero2"
我开发时，使用的是win10环境，目标框架是nf4.8，所以这个库能正常引用。而客户机上，安装了nf4.8的运行时，但搜索之后，发现客户机上并没有这个库。
为了适配客户机环境，我选择讲开发环境的这个库放到bin目录下，就能正常引入创建了。
浏览相关信息的时候，看到还有种解决思路，就是放弃使用该主题，感觉也是个思路，可以按需选择。
