由於核心1.0 RTM的更新，我現在不能更新數據庫：實體框架的核心1.0 RTM添加遷移失敗
dotnet ef migrations add CreatedJobcards
現在我得到這個錯誤：
System.TypeLoadException: Could not load type 'Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions' from assembly 'Microsoft.Extensions.DependencyInjection, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
我project.json看起來是這樣的：

UPDATE： 也發生在接下來的命令同樣的錯誤：
dotnet ef database update 0
dotnet ef migrations remove
更新2：包括數據庫內容檔案：

您能否顯示您的DbContext？ –
@VolkanSeçkinAkbayır我可以，但看到應用程序生成沒有問題，並且錯誤也發生在運行'dotnet ef數據庫更新0'，我真的不認爲這是任何與** dbContext **。 然而，我將更新帖子，以包括那 – MerlinNZ
所以，DbContext有通過構造注入的依賴？ –
