升級後的ASP.NET MVC應用程序問題

Question

我已將ASP.NET應用程序升級到MVC 4.一切工作在我的本地計算機上。 但當我將應用程序部署到Web服務器，我得到了以下錯誤消息：

Server Error in '/' Application.

WRN: Assembly binding logging is turned OFF. 
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Answer 1

最可能的原因是因爲你引用那些文件只有在本地機器上，很可能在GAC中，所以當你部署到服務器時，它找不到它們。

看看你的MVC引用的屬性窗口，看看是否有任何GAC。

要解決此問題，請在引用的屬性窗口中將對System.Web.Mvc的引用標記爲「copy local = true」。然後，當您部署/構建安裝程序時，它會將引用的文件複製到bin文件夾中，因此將在服務器上可用。

對所有MVC文件重複此過程。

您需要將大量程序集部署到部署的應用程序的bin文件夾中。 See this blog post或谷歌的「部署mvc程序集」獲取更多信息。
