EF降級：無法加載文件或程序集'EntityFramework'或它的一個依賴關係

Question

我一直在得到下面的錯誤和天爲了我不明白爲什麼。我沒有做任何改變，除了升級到Windows 10.我降級了我的EF和升級，以確保我有相同的版本，但沒有解決。我嘗試了所有選項，自己託管應用程序，但即使這樣也沒有幫助消除Visual Studio問題。

請感謝您的任何建議。

無法加載文件或程序集'EntityFramework'或其某個依賴項。因爲它被另一個進程 過程不能訪問該文件

更新： -得到了我的問題的修復，修復是消除映射並重新映射到另一個文件夾。出於某種原因，舊文件夾保存了dll的加載。

您的EntityFramework DLL正在被系統中的另一個程序使用。這是編譯時無法在bin中加載此程序集的原因。我無法分辨哪個程序正在使用此dll。你的機器中是否安裝了Panda AV？如果是禁用它，並嘗試如果它的工作。
