teamcity - 构建服务器上的 ASP.NET Core 2.0 项目的 Nuget 恢复失败

Question

我正在尝试在 Windows Server 2012R2 上使用 TeamCity 为 .NET Framework 4.6.2(不是 .NET Core)构建 ASP.NET Core 2.0 应用程序。

服务器中安装了以下组件:

• Microsoft .Net Core SDK - 2.0.0.0
• Microsoft .Net 框架(4.5.2、4.6、4.6.2)
• Microsoft 构建工具(2013 年、2015 年、2017 年)
• Windows SDK 10.0
• ...

TeamCity 使用 nuget 4.1 版和解决方案文件来恢复依赖包(有关详细信息，请参阅下面的完整日志)。

错误:

问题:

我认为 .NET Framework 4.6.2 实现了 .NET Standard 2.0，因此我不明白为什么这些包不兼容。在我的本地计算机(使用 Visual Studio 2017 Update 3 (15.3))上，nuget 恢复工作正常。

有什么想法可以解决该错误/如何进一步分析问题吗？

项目文件(包含 nuget 包):

使用 Nuget 4.3 版本修复了这个问题:)。
