無法加載文件或程序集System.Web.Mvc

Question

我在我的項目中使用umbraco 4.11.3。我的項目在Windows 7上運行得很好，並在Visual Studio 2012中運行它。 但它沒有工作從Visual Studio 2012運行時贏得8！

錯誤是：

注：在IIS上發佈的項目運作良好的Win7和Win8的。 我的項目不是基於ASP.NET MVC。 請幫幫我。

Answer 1

我們使用Azure雲來運行部署，並且出現同樣的錯誤。由於您無法真正將軟件包安裝到服務器實例上，因此解決此問題的方法是進入您的項目的參考，查找對抱怨缺失的庫的引用，進入屬性，然後將Copy Local設置爲True。重新部署，你全都準備好了。

Answer 2

我假設這是一臺新機器，看到你有新的操作系統和不同版本的Visual Studio。我認爲你需要安裝MVC Framework版本2，因爲這是你的Umbraco安裝所期望的。您可以安裝框架，並將DLL導入到您的GAC中，或者將您的良好系統中的DLL複製到Web應用程序的bin文件夾中。

注意，你說你的項目「不使用」MVC，但我認爲你會發現Umbraco。無論如何，這個錯誤告訴你係統希望找到它。

Umbraco 4.11.3不使用MVC2，它使用MVC3，所以我猜你在你的web.config中有一個引用到MVC2庫，可能在compilation > assemblies部分。它應該看起來像這樣：

<compilation defaultLanguage="c#" batch="false" targetFramework="4.0" debug="true"> 
    <assemblies> 
    <!-- ASP.NET 4.0 Assemblies --> 
    <add assembly="System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> 
    <add assembly="System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />

此問題的正確解決方法是：

1. 上References在Solution Explorer右鍵單擊並選擇Manage NuGet Packages
2. 在左側選擇Updates
3. 在中間部分選擇Microsoft ASP.NET MVC
4. 您應該看到一個Update按鈕出現在您的選擇中，點擊它

就是這樣......接受任何可能彈出的T & Cs，或者在本地發佈或運行您的項目。如果您在本地運行項目時仍遇到問題，請嘗試關閉Visual Studio，刪除該項目的.SUO文件，然後再次嘗試打開該解決方案...嘗試再次運行。
