C# AspNetCore-.xproj输出路径

我一直在尝试逐步了解一些开源MVC/ASP.NET核心代码，但每次我偶然发现一些新项目，在完成

git克隆后，我需要编辑
.xproj
文件以更改以下输出

<OutputPath Condition="'$(OutputPath)'=='' ">..\..\artifacts\bin\</OutputPath>

否则我会得到以下错误

Severity: Error
Code:
Description:
C:\Users\lndco\Documents\GitHub\RazorBlog\src\RazorBlog\error 
CS0006: Metadata file
'C:\Users\lndco\Documents\GitHub\RazorBlog\Mvc
\src\Microsoft.AspNetCore.Mvc.Formatters.Json
\bin\Debug\netstandard1.6\Microsoft.AspNetCore.Mvc.Formatters.Json.dll' 
could not be found    
Project: RazorBlog
File: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Common.Targets

使用VS 2015更新3

为什么MsBuild无法确定引用程序集的输出是
。\..\artifacts\bin\

文件夹：
global.json
AspNetCore poroject.json
忘记xproj和project.json的概念吧。安装VS2017并将所有这些迁移到最新的.NET Core SDK和MSBuild项目格式，这样您就不会在过去浪费时间了。请尝试一下，谢谢！
