使用 VS2017 在 windows 10 上从 github 构建 aspnet 核心源代码
Building aspnet core sources from github on windows 10 with VS2017
我想深入研究托管在 gihub 上的 asp.net 核心资源。
所以拿 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 b运行ch:
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（我可能错了）的 SDK，但这里是 authentication.csproj:

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，但事情似乎再也没有那么简单了。
运行 build.ps1 似乎安装了一些东西，然后 build.cmd 似乎执行了，我在 VS2017 中加载了解决方案。我无法构建任何东西。
错误 window 目前因一组错误而变得疯狂，这些错误似乎陷入了从 10 上升到 88，然后又回到 10 的无限循环中。
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。谁能提醒我构建它们需要什么？来晚了，辛苦了一天，眼睛疼

问题现在有点过时了。我写这篇文章是为了子孙后代。
描述：
我在以下之后得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
-正在下载并安装.NET Core 2.0
-合并更新的分支
-做一个干净的构建
解法：
我检查了项目属性，发现 .NET Core 2.0 安装没有出现在 "Target Framework" 下拉列表中。
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。
我想深入研究托管在 gihub 上的 asp.net 核心资源。
所以拿 asp.net core security 可以在这里找到 - https://github.com/aspnet/Security.

问题现在有点过时了。我写这篇文章是为了子孙后代。
描述：
我在以下之后得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
-正在下载并安装.NET Core 2.0
-合并更新的分支
-做一个干净的构建
解法：
我检查了项目属性，发现 .NET Core 2.0 安装没有出现在 "Target Framework" 下拉列表中。
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。
