c# - 缺少有关成功安装 NuGet 包的引用

Question

我正在关注这个guide设置我自己的 NuGet 私有(private)服务器，但使用 Visual Studio 2010。

我已经通过 Package Manager Console 成功添加了 NuGet.Server 包，但是当我想要构建 WebApplication 时出现错误:

The type or namespace name 'Server' does not exist in the namespace 'NuGet' (are you missing an assembly reference?)

包安装没有报错，但是我看到项目的reference文件夹里没有添加NuGet.Server，这是为什么？

编辑:进一步调查包内容，我发现 NuGet.Server 没有 net40 的 lib。我可能需要 fork NuGet.Server source并在 net40 中编译它来解决这个问题。

这是我从 Package Manager Console 中获取的日志:

在目标框架设置为 .NET Framework 4.0 的项目中尝试使用 Visual Studio 2015 构建它时，我遇到了同样的错误。将目标框架设置为 .NET Framework 4.6.1 为我修复了它。

如果可能，我建议使用较新版本的 Visual Studio，或者通过命令行使用较新的框架本身对其进行编译。如果您希望稍后执行此操作，则此其他堆栈溢出答案可能会有所帮助。 How to build .NET 4.6 Framework app without Visual Studio installed?
