使用VS2017在windows 10上从github构建aspnet核心源

Question

我想深入研究在gihub托管的asp.net核心资源。

因此，以asp.net core security为例，这里可以找到- https://github.com/aspnet/Security。

我已经下载并安装了GitHub桌面。我已经在我的机器上本地克隆了回购程序。我正在查看开发部门：

​

​

我已经从https://www.microsoft.com/net/core/preview#windowscmd下载并安装了SDK，我认为这个项目的目标是(我可能错了)，但是下面是authentication.csproj：

<Project Sdk="Microsoft.NET.Sdk">

  <Import Project="..\..\build\common.props" />

  <PropertyGroup>
    <Description>ASP.NET Core common types used by the various authentication middleware components.</Description>
    <TargetFramework>netstandard2.0</TargetFramework>
    <NoWarn>$(NoWarn);CS1591</NoWarn>
    <GenerateDocumentationFile>true</GenerateDocumentationFile>
    <PackageTags>aspnetcore;authentication;security</PackageTags>
    <EnableApiCheck>false</EnableApiCheck>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Authentication.Core" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.AspNetCore.DataProtection" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.AspNetCore.Http" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.AspNetCore.Http.Extensions" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.Extensions.Logging.Abstractions" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.Extensions.Options" Version="$(AspNetCoreVersion)" />
    <PackageReference Include="Microsoft.Extensions.SecurityHelper.Sources" Version="$(AspNetCoreVersion)" PrivateAssets="All" />
    <PackageReference Include="Microsoft.Extensions.TaskCache.Sources" Version="$(AspNetCoreVersion)" PrivateAssets="All" />
    <PackageReference Include="Microsoft.Extensions.WebEncoders" Version="$(AspNetCoreVersion)" />
  </ItemGroup>

</Project>

有一个解决方案文件(Security.sln)和一个build.cmd、build.ps1、build.sh。我希望加载解决方案并进行编译，但事情似乎不再那么直接了。

运行了build.ps1 (似乎安装了一些东西)，然后运行了似乎正在执行的build.cmd，我在VS2017中加载了解决方案。我就是没什么可做的。

错误窗口目前正变得疯狂，一组错误似乎被困在一个循环中，从10上升到88，然后在一个无穷无尽的循环中返回到10。

我找不到任何关于建立这些解决方案的任何信息。有人能告诉我建造它们需要什么吗？很晚了，已经是漫长的一天了，我的眼睛受伤了。

以下是所选的错误/警告：

Answer 1

问题现在有点过时了。我是带着后人写这篇文章的。

描述：

最后，我得到了一堆类似的错误消息：

-Being通知一个特定的开发项目被更新为.NET Core2.0

-Downloading和安装.NET Core2.0

-Merging更新的分支

-Doing一个干净的构建

解决方案：

我检查了项目属性，并意识到.NET Core2.0安装没有出现在“目标框架”下拉列表中。

在我将VS2017更新到最新可用的修补程序之后，问题就消失了。在此之后，.NET Core2.0作为目标框架可用。
