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

I am trying to build an ASP.NET Core 2.0 application for .NET Framework 4.6.2 (not .NET Core) with TeamCity on Windows Server 2012R2.

服务器中安装了以下组件:

The following components are installed in the server:

• Microsoft .Net Core 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和解决方案文件来还原依赖程序包(有关详细信息，请参见下面的完整日志).

TeamCity uses nuget version 4.1 and the solution file to restore dependent packages (see full log below for details).

错误:

[22:57:51]Process exited with code 1

问题:

我认为.NET Framework 4.6.2实现了.NET Standard 2.0，因此我不理解为什么这些软件包不兼容.在我的本地计算机上(使用Visual Studio 2017 Update 3(15.3))，nuget restore可以正常工作.

I thought that .NET Framework 4.6.2 implements .NET Standard 2.0, therefore I don't understand why the packages are incompatible. On my local machine (with Visual Studio 2017 Update 3 (15.3)) nuget restore works fine.

任何想法如何解决该错误/如何进一步分析问题?

Any ideas how to solve that error / how to further analyze the problem?

项目文件(包含nuget程序包):
