我正在EF5中使用MVC 4 aspnet網站。 本地,一切都運行得很好,但是當我把它發佈到IIS並嘗試進入,我得到的錯誤'System.Data.Entity.Internal.AppConfig'的類型初始值設定項引發異常
「的類型初始爲‘System.Data.Entity.Internal.AppConfig’ 拋出例外。」
詳細的異常
出錯創建 的EntityFramework配置節處理程序:對的DbContext類型配置 'GdpSoftware.Server.Data.GdpSoftwareDbContext, GdpSoftware.Server.Data' 是在 應用程序配置中指定了多次。每個上下文只能配置一次。 (E:\軟件\ web.config行104)
我在StackOverflow的檢查以前的問題,我已經卸載並通過的NuGet的EntityFramework重新安裝,並檢查了每個參考它在每一個項目都是EF5。我還檢查了每個項目中選定的框架是4.5。
任何想法,什麼可能會導致這個問題? 謝謝!吉列爾莫。

非常感謝指出了這一點......我一直在敲打着我的大腦。就試圖弄清楚爲什麼EF代碼首先是創造我上的LocalDB而不是在SQL Server數據庫就像我在我的connectionString已經指定 – levininja
我不得不這樣做,而且還添加提供程序是這樣的:' <提供商invariantName = 「System.Data.SqlClient的」 類型= 「System.Data.Entity.SqlServer.SqlProviderServices,EntityFramework.SqlServer」/> '爲[文檔](在指定http://msdn.microsoft.com/en-us /data/jj556606.aspx#Providers)。 –
