TFS 2018 构建失败，出现错误 MSB6006："csc.exe" 退出，代码为 1
TFS 2018 build failing with Error MSB6006: "csc.exe" exited with code 1
我最近构建了一个新的 TFS 2018（更新 3）服务器并添加了 Visual Studio 构建工具 (v15.7.1)。创建一个非常简单的 C# 项目后，服务器构建失败并显示错误 MSB6006："csc.exe" 已退出，代码为 1。我打开调试并发现了错误
Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp,
Version=2.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or
one of its dependencies. The system cannot find the file specified.
(TaskId:32)
我的项目没有引用这个库，我在项目级别关闭了代码分析，所以我认为这是 VS 构建工具的问题。有谁知道解决此问题的解决方法或方法？
我还注意到更新版本的 VS Build Tools (v15.8)。我还没有尝试更新构建服务器，因为生成离线包、压缩、上传等的复杂性很高，但如果找不到短期修复，我将进行下一次努力。
基本上，我们的新服务器在没有解决方案的情况下已经死了，所以我希望这里有人能给出答案，否则，我可能最终会为了更可靠的东西而放弃这一切。
似乎是版本 15.7.1 中的错误。目前尚不清楚是否有任何其他版本受到此错误的影响，但将 VS Build Tools 升级到 15.8.2 解决了该问题。
要发现错误 MSB6006 的根本问题：“csc.exe”以代码 1 退出，请在 MSBuild 参数中设置以下标志：
/v:diag
这将产生类似于以下内容的结果：
