由于'project.assets.json'没有.NETCoreApp,Version2.0的目标,TFS-CI构建失败

Question

我的控制台项目正在运行4.7.1(<TargetFrameworkVersion>v4.7.1</TargetFrameworkVersion>)

它引用了.NET Standard 2.0项目"TimeUtility":

解决方案在本地构建良好,但CI构建中出现以下错误:

项目"C:\ TFS\agent_work\21\s\Services\Daemons\ReportDaemon\ReportDaemon\ReportDaemon.sln"(1)正在构建"C:\ TFS\agent_work\21\s\Core\TimeUtility\src\TimeUtility \节点1上的TimeUtility.csproj"(14:15)(默认目标).PrepareForBuild:创建目录"bin\Release \netcoreapp2.0 \".C:\ Program Files(x86)\ dotnet\sdk\2.1.200\Sdks\Microsoft.NET.Sdk\build\Microsoft.PackageDependencyResolution.targets(167,5):错误:资产文件'C:\ TFS\agent_work\21\s\Core\TimeUtility\src\TimeUtility\obj\project.assets.json'没有'.NETCoreApp,Version = v2.0'的目标.确保还原已运行,并且已在项目的TargetFrameworks中包含"netcoreapp2.0".C:\ Program Files(x86)\ dotnet\sdk\2.1.200\Sdks\Microsoft.NET.Sdk\build\Microsoft.PackageDependencyResolution.targets(167,5):错误:资产文件'C:\ TFS\agent_work\21\s\Core\TimeUtility\src\TimeUtility\obj\project.assets.json'没有'.NETCoreApp,Version = v2.0'的目标.确保还原已运行,并且已在项目的TargetFrameworks中包含"netcoreapp2.0".[C:\ TFS\agent_work\21\s\Core\TimeUtility\src\TimeUtility\TimeUtility.csproj]完成构建项目"C:\ TFS\agent_work\21\s\Core\TimeUtility\src\TimeUtility\TimeUtility.csproj "(默认目标) - 失败.

我尝试过多种想法,但到目前为止已经成功了.
