無法加載文件或程序集'System.Web.Mvc'或其依賴項之一。 2個項目。 一次只能工作一個

Question

因此，我的解決方案中有2個網站項目（以及許多其他測試/ dll項目）。

項目A-CMS-標准Web項目（具有某些Web API集成）項目B-顯示站點-MVC 5。

我構建項目A，然后運行它。 它可以正常工作，沒有意外錯誤。 然后，我構建了項目B。項目B正常運行，再次沒有意外的錯誤。

我返回查看Project A上的內容，並在運行時收到以下錯誤。

無法加載文件或程序集'System.Web.Mvc'或其依賴項之一。 找到的程序集的清單定義與程序集引用不匹配。 （來自HRESULT的異常：0x80131040）

說明：執行當前Web請求期間發生未處理的異常。 請查看堆棧跟蹤，以獲取有關錯誤及其在代碼中起源的更多信息。

然后，我必須構建Project A以使其在運行時加載。 它可以工作，但是Project B也有同樣的問題。

我進入了Projects的/ bin /文件夾，發現有些奇怪。 說我正在查看項目A的/ bin

如果我生成Project A，則System.Web.Mvc.dll文件的版本為5.1.20129.0。如果我生成Project B，則相同的DLL文件將其版本后退一步。 至5.0.11001.0

使用此信息，我可以理解為什么會引發該錯誤，因為它認為該版本比那里的版本高。

而且，它沒有與我們的Git存儲庫同步，因為沒有其他開發人員遇到此問題。

任何人都知道這是如何開始的嗎？ 可能我該如何解決？

右鍵單擊解決方案，然后轉到“公共屬性”下的“啟動項目”，選擇“多個啟動項目”，選擇兩個項目。 這將同時運行項目並解決您的問題。
