Question

我正在尝试在TFS 2015.2中使用Visual Studio测试代理部署构建vNext任务。我在“测试”选项卡中添加了一个计算机组，但是当尝试在测试代理部署的构建任务的下拉列表中选择计算机组时，UI认为没有组！（点击下拉列表，不会显示任何内容）

我们刷新了页面并没有任何区别。这个问题似乎出现在所有构建任务中。我们尝试了Windows文件复制任务并手动输入了计算机组，任务成功，因此TFS确实识别了这些组。我作为TFS管理员遇到了这个问题。这种情况发生在我们安装的多个环境中。

还有其他人在使用TFS 2015.2时遇到过这个问题吗？

Answer 1

我不认为这个问题。尝试其他受支持的浏览器，看看是否会遇到同样的问题。

支持的浏览器：

Internet Explorer，版本9,10,11和12
Mozilla Firefox，最新版本（27）
谷歌浏览器，最新版本（32）
Safari（仅限Mac），版本7

同样的问题，我在微软论坛上发布了一个请求。

原因是对分布式任务协调员的调用：
