使用 VS2017 在 Windows 10 上从 github 构建 aspnet 核心源

Question

我想深入研究托管在 gihub 上的 asp.net 核心源代码。

所以请选择asp.net core security，可以在这里找到 - 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 repo。我在看开发分支：

我已经从 https://www.microsoft.com/net/core/preview#windowscmd 下载并安装了我认为项目目标的 SDK（我可能错了），但这里是 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编译，但事情似乎不再那么简单了。

运行了似乎安装了一些东西的 build.ps1，然后运行了似乎执行的 build.cmd，我已经在 VS2017 中加载了解决方案。我只是无法构建任何东西。

错误窗口目前正在变得疯狂，出现一组错误，这些错误似乎卡在一个循环中，从 10 上升到 88，然后在无限循环中回到 10。

我在任何地方都找不到有关构建这些解决方案的任何信息。谁能告诉我建造它们需要什么？时间不早了，累了一天，眼睛疼。

这里是错误/警告的选择：

Answer 1

问题现在有点过时了。我写这篇文章是为了后代。

说明：

之后我收到了一堆类似的错误消息：

-被通知特定开发项目已更新到 .NET Core 2.0

-下载安装.NET Core 2.0

-合并更新的分支

-进行干净的构建

解决方案：

我检查了项目属性，发现 .NET Core 2.0 安装没有出现在“Target Framework”下拉菜单中。

在我将 VS2017 更新到最新的可用补丁后，问题就消失了。之后 .NET Core 2.0 可用作目标框架。
