配置錯誤：System.Web.Helpers

我將站點部署到伺服器，但出現此錯誤。為什麼我會得到這個？

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.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

看起來您部署應用程序的伺服器沒有安裝 ASP.NET MVC 3。如果您不想在伺服器上安裝 ASP.NET MVC 3，您也可以bin 部署您的應用程序。

我遇到了同樣的問題，我從 Microsoft 站點安裝了 ASP.NET MVC 3 Tools Update，它解決了這個問題。

還要在安裝之前檢查 C:\Program Files (x86)\Microsoft ASP.NET 是否存在。就我而言，這個文件夾失去並且安裝後我有這個文件夾並且程序集已註冊。
