引用本机dll的C#7.0 MSbuild未知生成错误

Question

我有一个.net4.5项目，它是通过调用msbuild从控制台构建的。现在，构建目录可以包含(如果不进行干净的构建(额外的32位和64位dll文件。

到目前为止，该项目是使用C#5.0(VS2013(编译的，没有任何问题。我最近将该项目切换为使用C#7.0(VS2017(进行编译，并在构建目录包含本机dll时开始接收错误(XXXX-修订路径(：

Error: Command: "/cygdrive/C/XXX/4.0/15.0/Bin/MSBuild.exe c:/cygwin/home/XXXX/projmy_project.csproj

当使用/v:d运行msbuild时，我得到以下内容：

因此，出于某种原因，C#7.0编译器决定将构建目录中的所有dll作为依赖项，即使是.csproj文件中未引用的dll。

我真的很感激你能给我的任何指导，这已经折磨了我一段时间了，每次都做一次干净的打扮开始让人讨厌了。

感谢@PauloMorgado建议使用msbuildlog，我能够确定DLL被ImplicitlyExpandDesignTimeFacades项引用，在我的项目文件中添加<ImplicitlyExpandDesignTimeFacades>false</ImplicitlyExpandDesignTimeFacades>似乎解决了这个问题。

我不知道这个项目的真正含义或作用，但它有一个很长的名字和不想要的副作用。如果有人能评论一下这意味着什么，我将不胜感激。
