处理TypeLoadException而在启动

我在哪里我实现的功能将从appsetting.json读取值处理TypeLoadException而在启动

对于这种ASP.NET的核心应用工作读书AppSettings.json，我下面这个教程 - http://benjii.me/2016/04/new-configuration-appsettings-mvc6-web-config-gone/

从本教程中，我在下面way-

public IServiceProvider ConfigureServices(IServiceCollection services) 
{    
    services.Configure<AppSettings>(Configuration.GetSection("AppSettings")); 
}

在这个特别的线下自动绑定所有的应用程序设置 - services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));，我得到以下exception-

类型“System.TypeLoadException”的异常出现在 Microsoft.Extensions.OptionsModel.dll但在用户代码中没有处理

其他信息：未能加载类型 “Microsoft.Extensions.DependencyInjection。 ServiceCollectionExtensions' from assembly'Microsoft.Extensions.DependencyInjection.Abstractions， Version = 1.0.0.0，Culture = neutral，PublicKeyToken = adb9793829ddae60'。

显示你的' project.json' – haim770

haim770 added project.json – Vishal26

添加下面的包在你的project.json

"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0"

这个软件包包含OptionsConfigurationServiceCollectionExtensions类至极具有扩展方法IServiceCollection Configure<TOptions>
