有人知道是否可以将VS2019与TFS2018 vnext构建系统一起使用。您无法在构建定义中选择VS2019，但可以选择“最新”作为Visual Studio的版本。不幸的是，这并没有选择VS2019。
我已在安装了VS2017和VS2019的虚拟机中对此进行了测试。我还将TFS2018升级到Azure DevOps Server 2019，从而解决了这个问题。但这不是我们生产环境的“快速”解决方案。
这是我测试的日志。如您所见，选择“最新”作为Visual Studio的版本以及错误，没有选择任何VS：

这不是一个简单的解决方案。 changes required were pretty extensive。
正式地说，只有在将服务器升级到下一个更新版本或主要版本时才会升级内置任务。 TFS 2018更新3.2是TFS 2018的最新更新版本，并且鉴于Azure DevOps Server 2019（TFS的新名称）刚刚发布，我预计如果有任何新版本的任务将发布给TFS 2018更新4看到光芒。
注意这可能会在以后升级到其他服务器版本时导致问题，可能需要更新版本的Azure管道代理并且可能会使您处于不受支持的状态。
您可以克隆Azure Pipelines Tasks repo，在本地构建它，然后使用tfx-cli升级服务器中的内置任务。
git clone https://github.com/Microsoft/azure-pipelines-tasks.git
cd azure-pipelines-tasks
npm install
npm run-script build --task MSBuildV1
npm run-script build --task VstestV2
npm run-script build --task VSBuildV1
npm install tfx-cli@latest -g
tfx build tasks upload --task-path .\MSBuildV2 --service-url {{https://server/tfs/collection}}
tfx build tasks upload --task-path .\VsTestV2 --service-url {{https://server/tfs/collection}}
tfx build tasks upload --task-path .\VsBuildV1 --service-url {{https://server/tfs/collection}}
对服务器上的每个Project Collection重复此操作。
