我正在使用VS2015將ASP.NET 5應用程序部署到Azure。在成功部署並在瀏覽器中打開我的網站後，我收到錯誤：ASP.NET 5/Azure錯誤：FileNotFoundException：無法加載文件或程序集System.Data.SqlClient
FileNotFoundException: Could not load file or assembly 'System.Data.SqlClient, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. 該程序集未在我的項目中直接引用。它是通過EntityFramework.MicrosoftSqlServer程序集間接依賴的。
我有類似的問題使用ASP.NET 4在這裏解釋：Error: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient' 解決方案名爲「可怕的黑客」然後爲我工作。 :)
你有什麼想法可能會導致這個問題，以及如何解決它？
這裏是我的web應用程序project.json的內容：
{

"version": "1.0.0-*",

"scripts": {

}
}
和MyProject.Web是取決於該MyProject.Data項目project.json：
{
"version": "1.0.0-*",
"description": "MyProject.Data Class Library",
"authors": [ "f012rt" ],
"tags": [ "" ],
"projectUrl": "",

"System.Runtime": "4.0.21-beta-23516",
"System.Threading": "4.0.11-beta-23516"
}
}
},
"commands": {
"ef": "EntityFramework.Commands"
},
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",

"Microsoft.Extensions.Configuration.Json": "1.0.0-rc1-final",
"System.Runtime.Serialization.Primitives": "4.1.0-beta-23516",
"System.Data.SqlClient": "4.0.0-beta-23516" <-- I've tried with this explicit dependency here
}
}
我已經試過明確指定缺少的依賴項，正如你可以從我的project.json文件中看到的那樣。我可以確認包「System.Data.SqlClient」：「4.0.0-beta-23516」位於我的[approot] \ packages文件夾中。包文件夾在我的本地計算機上看起來完全如此。我已經嘗試在新創建的Web App上進行部署，以避免由於舊版本引起的任何問題。錯誤仍然是一樣的。
這可能是最清晰的可執行文件m –
