C# 升级到AspNet 5 RC1-update1后对SqlServerDbContextOptionsBuilder的调用不明确

我想将我的项目从asp.net beta-7升级到asp.net 5 RC1-update-1，但在我的

startup.cs

中出现了两个错误：

public void ConfigureServices(IServiceCollection services)
{
   // Add Entity Framework services to the services container.
   services.AddEntityFramework()
            .AddSqlServer()
            .AddDbContext<ApplicationDbContext>(options =>
           options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));
}

My project.json：

"webroot": "wwwroot",

在jour

project.json

中似乎有一个重复的条目，尽管由于dll名称发生了更改，这并不明显：

以前的“EntityFramework.SqlServer”现在是：

“EntityFramework.MicrosoftSqlServer”

所以只要把线去掉就行了

"EntityFramework.SqlServer": "7.0.0-beta7",

你应该准备好了。

你可以分享你的project.json吗？当然可以，用我的project.json查看我的更新答案。仅供参考，我已删除userSecretsId

"EntityFramework.SqlServer": "7.0.0-beta7",
