在我的解决方案中，许多项目使用Fody来注入PropertyChanged编织器。不幸的是，在构建结束时，当Fody开始编写最终程序集时，进程挂起并且无法恢复。

这是我正在执行的 MSBuild 命令：

set msbuildemitsolution=1
msbuild MyCompany.App.sln /t:Build /fl /flp:logfile=buildoutput.txt;verbosity=diagnostic /p:Configuration=Debug /p:Platform="Any CPU" /p:UseSharedCompilation=false

这是构建的日志：

如果我尝试取消构建，它将在这种状态下永远挂起CTRL-C我收到以下消息：

Attempting to cancel the build... 
warning MSB4220: Waiting for the currently executing task "Fody.WeavingTask" to cancel.

该过程将继续尝试每 10 秒左右取消一次构建，但未成功。MSBuild 任务变得无法杀死，我需要重新启动机器才能尝试启动另一个构建！

该项目使用以下内容：

  • Fody.3.0.3
  • PropertyChanged.Fody.2.4.0

我使用的 msbuild 版本是16.4.0.56107

我尝试更新到最新的 Fody 版本，但没有帮助。

我知道这可能是一个长镜头；如果有人对如何调查此问题有任何提示/想法，请分享。谢谢你。

-- 编辑 -- 如果我从失败的项目中删除 PropertyChanged 和 Fody，则解决方案可以完成构建。什么可能导致 Fody 上吊？

不幸的是，我无法隔离问题；考虑到 Fody 不仅仅在我们的一个项目上工作，我最终用BindableBase该类提供的 .Net 实现替换了 Fody 和 PropertyChanged

    private string title;
    public string Title 
    { 
        get => title;
        set => SetProperty(ref title, value);
    }

不确定这是否有帮助，但是我们注意到一些干扰可能来自硬盘驱动器根目录中没有扩展名的文件。从类似的东西看c:\Progra~1orc:\Program并重命名或删除它

使用带有完全过时版本的 Fody 的最新编译器很可能会导致这种情况 - Fody（通过 Mono.Cecil）可能无法处理生成的 IL。
