Fody写入程序集时，MSBuild将永远挂起

在我的解决方案中，许多项目使用Fody来注入PropertyChanged weaver。不幸的是，在构建结束时，当Fody开始编写最终程序集时，该过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

这是生成的日志：

在这种状态下它将永远挂起，如果我尝试用CTRL-C取消构建，我会收到以下消息：

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

进程将继续尝试每隔10秒左右取消生成，但未成功。MSBuild任务变得不可修改，我需要重新启动计算机以尝试启动另一个生成

本项目利用了以下内容：

• 福迪3.0.3
• PropertyChanged.Fody.2.4.0

我使用的msbuild版本是16.4.0.56107

我试图更新到最新的福迪版本，但没有帮助

我知道这可能是一个漫长的过程；如果有人对如何调查此事有任何建议/想法，请分享。多谢各位

如果我从失败的项目中删除PropertyChanged和Fody，那么解决方案就可以完成构建。什么可能会导致福迪被绞死？

不幸的是，我还没能找出问题所在；考虑到Fody不仅仅在我们的一个项目上工作，我最终用

BindableBase

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根目录中没有扩展名的文件。

从类似于

c:\Progra~1

或

c:\Program

的地方看，将其重命名或删除很可能是使用最新的编译器和完全过时的Fody版本导致的，Fody（通过Mono.Cecil）可能无法处理生成的IL。

存在此问题，无法通过任何方式解决。有人有突破吗？出于好奇。。。您的硬盘根目录中是否有一个没有扩展名的文件？查找类似于

C:\Program

或

C:\Progra~1

的文件。不，我没有这样的文件。在我的情况下，我也尝试更新到最新版本的Fody-没有成功
