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。该项目可以在具有完全相同版本的Visual Studio 2017（26430.13）的不同机器上构建。唯一的区别是，目前我试图在Windows 10上构建。其他系统（可以构建）是Win 8.1。但是在Win 10的第三台机器上也可以构建。VS 2017 c＃错误CS0234名称空间中不存在类型或名称空间名称（缺少程序集引用吗？）
我的问题是在系统上之后，无法构建解决方案：
有一个名为ucx.v2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。
还有另一个名为Timer的项目。该项目在参考文献中提及了ucx.v2。它没有损坏。当我构建这个项目时，我得到了超过100个错误，关于参考错误。
构建顺序是正确的，因为当我构建Timer项目时，首先它开始构建ucx.v2项目，并且完成没有任何错误。
我试过以下内容： - 重新启动VS. - 清理解决方案，重建项目 - 删除Timer项目的引用，并再次添加 ，但没有任何运气。
注意：我已经从工作机器复制了解决方案。
以下是错误日志：
