Answer 1

请参阅以下步骤:

添加 NuGet 安装程序 (4.0.0) 任务以还原包

添加 Visual Studio 构建任务(解决方案:**\*.sln；MSBuild 参数:/t:[projects] /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactstagingdirectory)\\App1")。 注:projects是该方案中的通用.net框架项目，如/t:project1;project2

添加 .NET Core 任务(命令:publish；取消选中 发布 Web 项目选项 ；项目:$(build.sourcesdirectory)/*Core*.csproj(0x1045 到 679191914 个项目)0x1045 到 679104040679191919 项目名称:04040679191940404000

添加发布构建工件任务
