Question

我一直得到下面的错误，为了天堂，我无法弄清楚为什么。除了升级到Windows 10之外，我没有做任何更改。我降级了我的EF并升级以确保我有相同的版本，但没有解决。我已经尝试了所有选项，自己主持了应用程序，但即便如此也没有帮助消除Visual Studio问题。

请欣赏任何建议。

更新： - 修复了我的问题，解决方法是删除映射并重新映射到另一个文件夹。出于某种原因，旧文件夹正在装载dll。

Answer 1

您的EntityFramework DLL正由系统中的其他程序使用。这是您在编译时无法在bin中加载此程序集的原因。我不知道哪个程序当前正在使用这个DLL。你的机器上安装了Panda AV吗？如果是，请禁用它并尝试它是否有效。
