我看过这篇文章,但错误与我的不同。

Error while adding AddOptions in Startup.cs

我的错误是:

我的代码是:

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

public static IServiceProvider svcProvider = null;

private static void LoadDIStartup()
{
    //Dependency Injection Setup Start
    var env = Environment.GetEnvironmentVariable("ASPNET_ENVIRONMENT");
    Console.WriteLine("ASPNET_ENVIRONMENT: {0}", env);
    var configuration = new ConfigurationBuilder()
        .AddJsonFile("appsettings.json", optional: false)
        .Build();


    svcProvider = new ServiceCollection()
        .AddOptions()
        .Configure<AppConfig>(configuration.GetSection("AppConfig"))
        .AddConfigFile()
        .BuildServiceProvider();

    IgniteDependencyResolver.SetProvider(svcProvider);
    IgniteDependencyResolver.SetConfiguration(configuration);
    IgniteDependencyResolver.Bind<AppConfig>();
    //Dependency Injection Setup End

}
