Nuget無法更新.NET Core項目

Question

我安裝了.NET Core，並使用ASP.NET核心Web應用程序（.NET Core）模板創建了一個新的VS2015項目。

這個基礎項目編譯和運行得很好，在參考文獻部分沒有任何奇怪的錯誤。

然而NuGet包管理器用戶界面標識了十三個更新。大膽地/我天真的PM控制檯上執行此命令：

Update-Package 

它輸出就在這個問題（爲了簡潔）的底部顯示成功消息的這個漂亮的長長的名單，並在project.json更新的版本號。

這裏是project.json依賴關係部分：

"dependencies": { 
    "Microsoft.ApplicationInsights.AspNetCore": "1.0.2", 
    "Microsoft.AspNetCore.Mvc": "1.1.0", 
    "Microsoft.AspNetCore.Routing": "1.1.0", 
    "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0", 
    "Microsoft.AspNetCore.Server.Kestrel": "1.1.0", 
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0", 
    "Microsoft.Extensions.Configuration.FileExtensions": "1.1.0", 
    "Microsoft.Extensions.Configuration.Json": "1.1.0", 
    "Microsoft.Extensions.Logging": "1.1.0", 
    "Microsoft.Extensions.Logging.Console": "1.1.0", 
    "Microsoft.Extensions.Logging.Debug": "1.1.0", 
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0", 
    "Microsoft.NETCore.App": { 
     "version": "1.1.0", 
     "type": "platform" 
    } 
    }, 

在Solution Explorer中雖然，包版本不更新。

當我重建，我得到的警告令，所有的格式如下：

warning NU1007: Dependency specified was Microsoft.AspNetCore.Mvc >= 1.1.0 but ended up with Microsoft.AspNetCore.Mvc 1.0.1. 

我不明白爲什麼會的NuGet更新的package.json，但不是項目引用。而且，我不知道如何手工修復它。雖然project.json更新，project.lock.json不大，但通過改變手的版本號也將導致警告變成錯誤的形式：

NU1001 The dependency Microsoft.Extensions.Logging.Console >= 1.1.0 could not be resolved. 

我使用VS2015更新3和3.5的NuGet。

我的問題，然後：

1. 有沒有辦法強制的NuGet更新項目引用，所以我不會得到這些警告？
2. 任何想法爲什麼發生這種情況？
3. 是否有可靠的解決方法（如手動編輯某些文件）？

下面是Update-Package輸出：

你試過dotnet restore？第二件事是你有最新的.Net Core。嘗試下載並安裝SDK的最新版本
