我正在尝试使用 CLI 构建我的 .NET Core 应用程序dotnet build，但每次我都会收到此错误：
“IConfigurationBuilder”不包含“AddEnvironmentVariables”的定义，并且找不到接受“IConfigurationBuilder”类型的第一个参数的扩展方法“AddEnvironmentVariables”（您是否缺少 using 指令或程序集引用？）
这是我的ConfigureServices中的方法Startup.cs问题发生的地方：
public void ConfigureServices(IServiceCollection services)
{
var builder = new ConfigurationBuilder()
.AddJsonFile("config.json")
.AddEnvironmentVariables()
.Build();
services.AddEntityFrameworkSqlServer()
.AddDbContext<MyContext>(options =>
options.UseSqlServer(builder["Data:MyContext:ConnectionString"]));
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddEntityFrameworkStores<MyContext>()
.AddDefaultTokenProviders()
.AddOpenIddictCore<Application>(config => config.UseEntityFramework());
services.AddMvc();
services.AddScoped<OpenIddictManager<ApplicationUser, Application>, CustomOpenIddictManager>();
}
看着这个例子 https://github.com/openiddict/openiddict-core/blob/dev/samples/Mvc.Server/Startup.cs我没有发现我的明显问题Startup.cs.

2018 年 10 月更新：在 VS 2017 的最新版本中创建新的 .NET Core 2.1 应用程序时，不会出现此问题。自从我提出这个问题以来，一切现在都处于长期稳定的版本。
