【问题描述】：
我有一个包含多个项目的解决方案。我有正确的构建顺序和依赖关系。此项目可以在具有完全相同版本的 Visual Studio 2017 (26430.13) 的不同计算机上构建。唯一的区别是，目前我正在尝试在 Windows 10 上构建。另一个系统（可以构建）是 Win 8.1。但是在装有 Win 10 的第三台机器上也可以构建。
我的问题是系统上的以下问题，无法构建解决方案：
有一个名为 ucx.v2 的项目（命名空间：pcbox）。当我构建这个项目时，没有错误并且构建正确。
还有一个名为 Timer 的项目。该项目在参考资料中有对 ucx.v2 的参考。它没有坏。当我构建这个项目时，我收到了 100 多个关于参考错误的错误。
构建顺序是正确的，因为我在构建Timer项目时，首先开始构建ucx.v2项目，并且没有任何错误完成。
我尝试了以下方法： - 重新启动 VS。 - 清洁解决方案，重建项目 - 从 Timer 项目中删除引用，然后重新添加 没有任何运气。
注意：我已经从工作机器上复制了解决方案。
这是错误日志：

【问题讨论】：
-
您找到解决方案了吗？
-
我自己也有类似的问题 - 直到我复制并与主 TFS 分支合并之前，我的解决方案正在编译（不确定哪个操作导致了错误）。我有问题的 dll 是 Newtonsoft，它正在针对 .net framework 4.0 的解决方案中使用（因此它应该并且工作正常），该解决方案生成的 dll 与 newtonsoft.dll 一起用于另一个突然遇到该警告的解决方案和错误。当我转到代码编辑器时，“使用”中的红色波浪线消失了，错误量减少了几项，仍然 - 无法构建解决方案。
