我创建了一个ASP.NET MVC 3应用程序,我在DAL中有一个ADO.NET实体数据模型,其中包含用于访问数据的类。
我还有一个WCF restful服务,我创建用于与我的Android应用程序进行通信。因此,当我尝试在IIS7上托管我的服务时,我收到了这个错误:
底层提供程序在Open上失败,在这里:
服务器在处理请求时遇到错误。异常消息是“基础提供程序在打开时失败”。请参阅服务器日志以获取更多详异常堆栈跟踪位于

对于旁注,当我从Visual Studio启动它时,我的WCF服务没有问题,问题仅在于IIS。当我搜索这个问题时,我尝试了这些提出解决方案的东西:
我也尝试过在这些链接中提出的所有解决方案仍然没有工作:
也是这个:
如果有人可以提供帮助,我会非常感激。

请注意,它是WCF restful APPLICATION 而不是库,我也在VirtualBox中的Windows 7 Ultimate 64位下运行。
答案 0 :(得分:0)
需要你的确认......, 您在连接字符串中使用mdf文件,IIS服务器在哪里,是否在您使用Visual Studio运行应用程序的同一台计算机上。?
如果你在不同的物理盒上托管,那么.mdf文件就存在完整路径.....下面是你共享web.config中连接字符串的一部分,你应该首先验证文件的退出..... data source =(localDB)\ v11.0; attachdbfilename = C:\ Users \ ines \ Documents \ Visual Studio 2012 \ Projects \ GestionDeComptabilite \ DataRepository \ App_Data \ GestionComptabilite.mdf; MultipleActiveResultSets = True; App = EntityFramework“
