为什么我收到“无法加载指定的元数据资源”错误？

Question

我有一个MVC5的Web应用程序，我通常使用我的笔记本电脑开发。

我试图让应用程序在主场以家庭为工作日我的主要机器上运行，但有连接到本地开发数据库SQL Server上的一个问题 - 当我启动应用程序，我得到以下错误：

更多信息30/11/16：

注意，该模型是从EDML使用实体开发

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.

解决方案包括2个项目，w的一种产生这是一个由EDMX生成的实体模型项目。

注：在我的主机（如果它不工作）在Web.config连接字符串是一样的地方工作，除了Data Source这是指SQL Server名称的主要机器对机器 - 我已经检查了这是正确的几次：

我已看过一些堆栈溢出的职位有类似的问题 - 最点到一些错误的路径csdl，ssdl，连接字符串的msl一部分。

我：

• 经过服务器名称是经过数据库名称连接字符串
• 在正确的是经过数据库中存在连接字符串
• 在正确的和可
• 经过这三个文件中的每一个都是连接字符串所表示的位置（它们是）
• 在连接字符串中使用通配符尝试：res://*/dllname.csdl|res://*/dllname.ssdl|res://*/dllname.msl

更新30/11/2016：

从建议中this link我：

• 经过的MetadataArtifactProcessing属性 - 它没有被设置为Copy to Output directory
• 检查连接字符串
• 我们没有后期编译任务

从this link的建议，我已经尝试设置连接字符串connectionString="metadata=res://*/;

有一个非常流行的问题over there和其评级我可以假设它帮助了很多的人。它甚至提到了一个完整的解决这个问题的博客文章。另外，this answer看起来像你还没有尝试过的东西。
