我正在尝试回滚我的C# Winforms .slnx解决方案，以找出是哪个仓库提交引入了一条无关的错误。当我回滚到大约六周前曾经工作的版本时，应用在启动时崩溃，绕过了我的未处理异常处理程序（UnhandledExceptionHandler）。回滚时，我会看到一条消息：“此解决方案包含具有漏洞的包……”，这条信息（在它正常运行时也出现过，这也是我最初升级的原因）。Visual Studio显示的唯一崩溃信息是："The program '[38596] PixEmail.exe' has exited with code 2147483651 (0x80000003)."

通过手动编辑崩溃版本的.csproj文件，我确定崩溃的原因是

降级为："<PackageReference Include="CefSharp.WinForms.NETCore" Version="146.0.70" />"

至："<PackageReference Include="CefSharp.WinForms.NETCore" Version="145.0.250" /> "

Cef的日志显示了一些错误，但工作版本和崩溃版本的日志很相似：

工作版本：

是什么原因让六周前在Visual Studio中能够正常运行的应用现在会失败？我该如何让降级后的版本再次运行？

顺便说一句，我并不关心所报告的漏洞。我是在一个受沙箱保护的环境中进行降级，以诊断一个不相关的问题。

解决方案

你遇到了来自本地代码中调试断言或有意崩溃的 __debugbreak() 或int 3指令。尝试清理版本145.0.250的 NuGet包缓存。之后重新构建项目。

nuget locals all -clear

dotnet restore
