2.5天，我试图找出等错误的根源
Could not load file or assembly "mydll.dll" or one of its dependencies.
The specified module could not be found
该项目是一个基于Windows C#的应用程序。该dll是在项目内部的C++库中创建的。我使用VS2017 Entreprise在Windows 10 64位下编译，在Windows 7 64位下部署有问题(在Windwos 10下部署很好…(。所有.NET libs/exes/plugins都以.NET 4.5.2为目标(安装在部署计算机上(。图书馆使用
Windows SDK Version: 8.1
Platform Toolset: Visual Studio 2017 (v141)
该项目制作了一个msi安装程序，我成功地将其安装在部署计算机上。dll当然在那里。
所以我用进程监视器观看了程序的执行。dll似乎加载了好几次。我最后一次看到以下内容。

谷歌告诉我，所有这些都与这个问题无关。。。现在，使用nm-D和ldd在linux下2.5分钟内完成任务需要2.5天。。。
在尝试从Windows 10高效地瞄准Windows 7 3天后，我分享了我的经验，并得出了以下答案：
这是Microsoft开发人员从未预见到的。MS已经提供了一些破解，但无法实现可靠的开发链。
- 在您将遇到的其他问题中，请查看此链接。。(说真的，你必须手动卸载Microsoft软件包才能进行Microsoft Update？说真的是Microsoft吗？(
- 截至2018年，还没有一个有效的工具可以告诉你微软世界缺少什么动态库(基本上没有等效的ldd(。。。甚至不要开始告诉我DependencyWalker或其他什么，它让位于太多的假阳性(>>100%信噪比(，并且已经过时了
这与这里不值得一提的1000个其他Microsoft典型问题(包冲突等(一起，导致这样做在理论上可能，但在实践中不是。(如果在Linux下几分钟内完成的事情需要数小时或数天，我认为这在实践中是不可行的(
我给读者的建议是，如果你需要以Win7为目标，那么就让自己成为Win7开发虚拟机。
当然，如果你的公司只能给你一个VS2017而不是2015，问题就会出现。这种困境对于微软来说是众所周知的，事实上这正是他们的目标。强迫您购买新产品，或者您的客户切换到新的操作系统。。。
Richard Critten的回答BTW与这个问题无关
