TFS2015 中的 xunit - ParallelizeAssemblies 的放置位置

我正在努力加快我们的单元测试。通过在 app.config 文件中设置xunit.parallelizeAssembly为truein，我可以从不同的程序集中获得多个测试，以便在从 Visual Studio 运行时并行运行。但是当在构建服务器上运行时，执行时间没有区别，我可以看到只使用了一个核心。

在上的MSBuild亚军段落此页面，建议该设置ParallelizeAssemblies将解决这个问题。我目前正在使用“Visual Studio 测试”构建步骤运行测试（配置请参见图片）。我把这个设置放在哪里？

我不能分享所有的日志，但我相信第一部分和最后一部分可能包含很好的线索。
