调试反射类型加载异常
Debugging Reflection TypeLoadExceptions
如何调试此类错误？
问题文件是System.Memory，版本=4.0.1.1。据我所知，我在我的任何项目中都没有引用这个文件，我已经检查了我导入的 nuget 包的依赖关系，其中 none 个引用了这个文件。
为什么要加载此文件？令人沮丧的是，在带有 ReflectionTypeLoadException 的 InvalidOperationException 中抛出的错误只是一条消息。我无法访问抛出的错误，因为它是在我无权访问的 DLL 中抛出的。该 DLL 构成了我公司框架的一部分。
我有一个非常相似的项目，它使用相同的公司框架 DLL，但没有这个问题。
错误：

遵循 Alexei Levenkov 的指示：
我能从 NuGet 获得的 System.Memory 的最早版本是 4.4.0，而不是 Framework。因此，我在解决方案资源管理器中检查了 2 个有问题的项目中的引用，并注意到 System.Memory 4.0.1.0。我很生气忽略了这一点，但是，删除该引用并添加 4.0.1.1 有效并且错误不再发生。
现在我需要弄清楚项目中的哪些引用（不是 NuGet）使用 4.0.1.1 并将其删除。
我错过的重要线索在 Fuslogvw 日志的更下方：
日志：程序集名称是：System.Memory，版本=4.0.1.0，文化=中性，PublicKeyToken=cc7b13ffcd2ddd51。
如果对此给予更多关注，就会发现安装了早期版本，NuGet 中没有该版本，并且会导致我得出上述结论。
