在Windows 7上从Windows 10 VS2017部署编译并找不到DLL

问题描述 投票：-4回答：1

2.5天，我尝试了一个错误的根源，如

Could not load file or assembly "mydll.dll" or one of its dependencies.
The specified module could not be found

该项目是基于Windows C＃的应用程序。该DLL是在项目内的C ++库中创建的。我使用VS2017 Entreprise在Windows 10 64位下编译，并且在Windows 7 64位下部署有问题（Windwos 10下的部署工作正常......）。所有.NET libs / exes / plugins都以.NET 4.5.2为目标（安装在deployement计算机上）。图书馆使用

Windows SDK Version: 8.1
Platform Toolset: Visual Studio 2017 (v141)

该项目创建了一个msi安装程序，我在部署计算机上成功安装。当然dll就在那里。

所以我用过程监视器观察了程序的执行情况。这个DLL似乎被加载了好几次。我最后一次看到以下内容。

那个api-ms-win-core-localization-l1-2-0.dll确实是由依赖者walker一起列出的

API-MS-WIN-CORE-FILE-L1-2-0.DLL
API-MS-WIN-CORE-FILE-L2-1-0.DLL
API-MS-WIN-CORE-LOCALIZATION-L1-2-0.DLL
API-MS-WIN-CORE-PROCESSTHREADS-L1-1-1.DLL
API-MS-WIN-CORE-SYNCH-L1-2-0.DLL
API-MS-WIN-CORE-TIMEZONE-L1-1-0.DLL
API-MS-WIN-DOWNLEVEL-ADVAPI32-L1-1-0.DLL
API-MS-WIN-DOWNLEVEL-OLE32-L1-1-0.DLL
API-MS-WIN-DOWNLEVEL-SHLWAPI-L1-1-0.DLL
GPSVC.DLL
MSISO.DLL

谷歌告诉我，所有这些都与这个问题无关......现在用2.5分钟的时间用nm-D和ldd在2.5分钟内完成你的工作......

在尝试从Windows 10有效地定位Windows 7 3天后，我分享了我的经验，我得出以下答案： 这是微软开发人员从未预见过的。 MS提供了一些黑客攻击，但无法实现可靠的开发链。

  1. 你会遇到的其他问题，看看这个link ..（严重的是你必须手动卸载Microsoft软件包以进行Microsoft更新？严重的是Microsoft？）
  2. 截至2018年，没有一个有效的工具可以告诉你在Microsoft世界中缺少什么动态库（基本上没有相当于ldd）...甚至没有开始告诉我DependecyWalker或任何东西，它让路假阳性过多（>> 100％信噪比）并且已经过时。

这与在这里不值得一提的其他1000个微软典型问题（包冲突等）一起，导致说这样做在理论上可能是可能的，但实际上并不存在。 （如果你需要花费数小时或数天的时间来完成你在Linux下几分钟内完成的事情，我认为这几乎不可行）

我对读者的建议是，如果你需要针对Win7，那么自己做一个Win7开发虚拟机。

当然，如果你的公司只能得到一个VS2017而不是2015年，就会出现问题。微软已经知道这个困境，这实际上是他们的目标。强迫您购买新产品，或者您的客户切换到新的操作系统......
