錯誤而Startup.cs

Question

加入AddOptions

我想實現選擇圖案在這個環節提到 - https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration#options-example

當我Startup.cs

的

public void ConfigureServices(IServiceCollection services) 
    { 
     // Setup options with DI 
     services.AddOptions(); 

     services.Configure<AppSettingsModel>(Configuration); 

我得到ConfigureServices添加這兩條線下面調用如下方法或屬性無差錯 call is ambiguous error screenshot

我完全project.json之間的曖昧就像是這個 -

我的環境是 - VS2015 UPDATE3，.NET SDK的核心和1.0.0工裝preview2

我的項目模板 - ASP.NET的核心應用程序（.NET框架4.6.1）

能

人請在此引導我？

你必須從你的依賴刪除Glimpse。正如你可以看到NuGet它取決於Glimpse.Server和Glimpse.Serverdepends上Microsoft.AspNet.FileProviders.Embedded這是ASP.NET核心的過時的包，直到RC1版本。這些軟件包現在名爲Microsoft.AspNetCore.*。

這將導致這兩個（新老組件）得到獲取和編譯器不能確定使用哪一個。混合版本總是非常糟糕。
