Teamcity 生成服务器上ASP.NET Core 2.0项目的Nuget还原失败

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

TeamCity使用nuget版本4.1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：

我认为.NET Framework 4.6.2实现了.NET标准2.0，因此我不理解为什么这些包不兼容。在我的本地机器上（使用Visual Studio 2017 Update 3（15.3））nuget restore工作正常

有没有办法解决这个错误/如何进一步分析这个问题

使用Nuget 4.3版修复了它：）。

您使用的是从Nuget.org下载的Nuget.exe 4.3.0吗？我也有同样的问题，说所有新的AspNetCore和EntityFrameworkCore 2.0.0引用与net462不兼容，但VS2017中的nuget可以工作。我通过team city安装了nuget版本，如上所述。但我认为TeamCity是从nuget.org获得的。我在Azure DevOps（VSTS）上遇到了问题，并在恢复任务开始工作之前向作业代理添加了一个任务以获得nuget 4.3。令人困惑，因为它当然在我的机器上工作。谢谢。引用.NET4.6.1库的.NETCore2.2项目也有同样的问题。已在Azure DevOps中使用Nuget 4.4.1。升级到Nuget 4.9.3运行良好。
