绑定AuthenticationConfig引发异常

Question

我有这段代码：

using Microsoft.Extensions.Configuration;
using System;
using System.IO;
using System.Threading.Tasks;

var builder = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json");

var config = builder.Build();
var authenticationConfig = new AuthenticationConfig();
config.Bind(authenticationConfig);

我得到：

Severity    Code    Description Project File    Line    Suppression State
Error   CS1061  'IConfigurationRoot' does not contain a definition for 'Bind' and no accessible extension method 'Bind' accepting a first argument of type 'IConfigurationRoot' could be found (are you missing a using directive or an assembly reference?)    SandboxSecurityToken    C:\xxx\Program.cs   35  Active

我已经导入了Microsoft.Extensions.Configuration（请参阅：使用Microsoft.Extensions.Configuration）。知道可能缺少什么吗？谢谢！

您需要添加NuGet软件包Microsoft.Extensions.Configuration.Binder才能使其正常工作。
