我目前正在开发 ac# wpf 应用程序,它可以正常工作,直到我将 vhd c++ 包装类添加到我的项目中,女巫非常大,所以我没有在这里发布它,它本身就可以正常工作。在我的项目中,当添加类文件并运行我的程序时,我在这一行的实体框架中遇到错误

CDEnteties.Services.Add(service);

我收到一个错误{“无法从程序集‘cloud opeaner, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’加载类型‘STORAGE_DEPENDENCY_INFO_Union’,因为它包含偏移量 0 的对象字段,该字段不正确地对齐或重叠非对象字段。”:“STORAGE_DEPENDENCY_INFO_Union”} 我不知道这两个是如何相关的以及为什么会发生。

编辑:堆栈跟踪

看起来这与 EF 本身无关。您的程序集中似乎有一个无效的类型,而 EF 只是触摸它,因此它会爆炸。如果您尝试手动加载此类型(例如Console.WriteLine(typeof('STORAGE_DEPENDENCY_INFO_Union').FullName);),即使您的项目中没有 EF,您也会看到相同的异常。如果您不使用它,则需要修复类型或删除它(连同依赖它的代码)。
