爲什麼我收到「無法加載指定的元數據資源」錯誤？

Question

我有一個MVC5的Web應用程序，我通常使用我的筆記本電腦開發。

我試圖讓應用程序在主場以家庭爲工作日我的主要機器上運行，但有連接到本地開發數據庫SQL Server上的一個問題 - 當我啓動應用程序，我得到以下錯誤：

更多信息30/11/16：

注意，該模型是從EDML使用實體開發

Unable to load the specified metadata resource. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

解決方案包括2個項目，w的一種產生這是一個由EDMX生成的實體模型項目。

注：在我的主機（如果它不工作）在Web.config連接字符串是一樣的地方工作，除了Data Source這是指SQL Server名稱的主要機器對機器 - 我已經檢查了這是正確的幾次：

我已看過一些堆棧溢出的職位有類似的問題 - 最點到一些錯誤的路徑csdl，ssdl，連接字符串的msl一部分。

我：

• 經過服務器名稱是經過數據庫名稱連接字符串
• 在正確的是經過數據庫中存在連接字符串
• 在正確的和可
• 經過這三個文件中的每一個都是連接字符串所表示的位置（它們是）
• 在連接字符串中使用通配符嘗試：res://*/dllname.csdl|res://*/dllname.ssdl|res://*/dllname.msl

更新30/11/2016：

從建議中this link我：

• 經過的MetadataArtifactProcessing屬性 - 它沒有被設置爲Copy to Output directory
• 檢查連接字符串
• 我們沒有後期編譯任務

從this link的建議，我已經嘗試設置連接字符串connectionString="metadata=res://*/;

有一個非常流行的問題over there和其評級我可以假設它幫助了很多的人。它甚至提到了一個完整的解決這個問題的博客文章。另外，this answer看起來像你還沒有嘗試過的東西。
