【问题描述】：
我正在使用 VS2015 将 ASP.NET 5 应用程序部署到 Azure。成功部署并在浏览器中打开我的网站后，出现错误：
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.
我的项目中没有直接引用该程序集。它是通过 EntityFramework.MicrosoftSqlServer 程序集间接依赖的。
我在使用 ASP.NET 4 时遇到了类似的问题，这里解释了：Error: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient' 当时，名为“可怕的黑客”的解决方案对我有用。 :)
您对可能导致问题的原因以及如何解决问题有任何想法吗？
这是我的网络应用 project.json 的内容：
{
"userSecretsId": "aspnet5-MyProject.Web-<A guid goes here>",
"version": "1.0.0-*",
"compilationOptions": {
"emitEntryPoint": true
},
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",
"EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
"Microsoft.AspNet.Authentication.Cookies": "1.0.0-rc1-final",
"Microsoft.AspNet.Diagnostics.Entity": "7.0.0-rc1-final",
"Microsoft.AspNet.Identity.EntityFramework": "3.0.0-rc1-final",
"Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",
"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
"Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
"Microsoft.AspNet.Server.Kestrel": "1.0.0-rc1-final",
"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
"Microsoft.AspNet.Tooling.Razor": "1.0.0-rc1-final",

"Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-rc1-final",
"MyProject.Data": "1.0.0-*",
"System.Data.SqlClient": "4.0.0-beta-23516" <-- I've tried with this explicit dependency here
},
"commands": {
"web": "Microsoft.AspNet.Server.Kestrel",
"ef": "EntityFramework.Commands"
},
"frameworks": {
"dnxcore50": { }
},
"exclude": [
"wwwroot",
"node_modules"
],
"publishExclude": [
"**.user",
"**.vspscc"
],
"scripts": {
"prepublish": [ "npm install", "bower install", "gulp clean", "gulp min" ]
}
}
以及MyProject.Web所依赖的MyProject.Data项目的project.json：
{
"version": "1.0.0-*",
"description": "MyProject.Data Class Library",
"authors": [ "f012rt" ],
"tags": [ "" ],
"projectUrl": "",
"licenseUrl": "",
"frameworks": {
"dnxcore50": {
"dependencies": {
"Microsoft.CSharp": "4.0.1-beta-23516",
"System.Collections": "4.0.11-beta-23516",
"System.Linq": "4.0.1-beta-23516",
"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",
"EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
"EntityFramework.Core": "7.0.0-rc1-final",
"Microsoft.AspNet.Identity.EntityFramework": "3.0.0-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
}
}
我已尝试明确指定缺少的依赖项，正如您从我的 project.json 文件中看到的那样。我可以确认包 "System.Data.SqlClient": "4.0.0-beta-23516" 在我的 [approot]\packages 文件夹中。包文件夹在我的本地计算机上看起来与此完全相同。我已经尝试在新创建的 Web 应用程序上进行部署，以避免旧部署引起的任何事情。错误仍然相同。

这可能是最清晰的执行m

你能把你的project.json文件的内容贴出来吗？
