無法加載文件或程序集“Microsoft.Practices.EnterpriseLibrary.Common，Version=6.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35”或

Question

我嘗試在 VS2015 中使用 Enterprise Library 6.0 中的 Logging 並彈出以下異常。 參考 Microsoft.Practices.EnterpriseLibray.Common 已經添加在 VS2015 的參考資料中。

Server Error in '/' Application.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1055.0  

幫我弄清楚

Answer 1

您所引用的 DLL 可能是不同的版本，或者可能根本沒有被引用。

1. 嘗試刪除並重新添加引用。
2. 嘗試在屬性中將Version Specific設置為false 。

Answer 2

有同樣的問題，通過將參數“啟用 32 位應用程序”設置為“true”（在 iis 應用程序池的高級設置中）修復。

同樣正如@ViVi 已經提到的，嘗試再次添加引用並重建您的項目。

Answer 3

只是在這里記錄發生在我身上的事情。

對我來說，錯誤是：

無法加載文件或程序集 'Microsoft.Practices.EnterpriseLibrary.Common, Version= 5.0.514.0 , Culture=neutral, PublicKeyToken=31bf3856ad364e35' 或其依賴項之一。

這個 DLL 在我的解決方案中沒有被引用。

事實證明，在其他一些項目中添加了對Microsoft.Practices.EnterpriseLibrary.Data的引用，該引用對Common.dll具有內部依賴性。 因此，實際上，如果您也使用舊版本的其他 EnterpriseLibrary 功能（例如Logging和Caching ），則可能會發生此問題。
