處理TypeLoadException而在啓動

我在哪裏我實現的功能將從appsetting.json讀取值處理TypeLoadException而在啓動

對於這種ASP.NET的核心應用工作讀書AppSettings.json，我下面這個教程 - http://benjii.me/2016/04/new-configuration-appsettings-mvc6-web-config-gone/

從本教程中，我在下面way-

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

在這個特別的線下自動綁定所有的應用程序設置 - services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));，我得到以下exception-

類型「System.TypeLoadException」的異常出現在 Microsoft.Extensions.OptionsModel.dll但在用戶代碼中沒有處理

其他信息：未能加載類型「Microsoft.Extensions.DependencyInjection。 ServiceCollectionExtensions' from assembly'Microsoft.Extensions.DependencyInjection.Abstractions， Version = 1.0.0.0，Culture = neutral，PublicKeyToken = adb9793829ddae60'。

顯示你的' 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"

這個軟件包包含OptionsConfigurationServiceCollectionExtensions類至極具有擴展方法IServiceCollection Configure<TOptions>
