如何与Microsoft.Build.Execution.BuildManager并行构建？

Question

我正在尝试使用MsBuild应用程序接口来运行构建frpm C#。下面的代码似乎可以工作，但只运行单线程构建。我真的需要它来运行多线程。当我从命令行运行msbuild时，我可以使用/m开关来启动并行构建。我怎样才能通过编程实现同样的目标呢？

            var logger = new BasicLogger();

            var buildParameters = new BuildParameters()
            {
                Loggers = new List<Microsoft.Build.Framework.ILogger>() { logger },
                DetailedSummary = false,
                EnableNodeReuse = false,
                OnlyLogCriticalEvents = false,
                ShutdownInProcNodeOnBuildFinish = true
            };

            var globalProperties = new Dictionary<string, string>
            {
                { "Platform", platform },
                { "Configuration", configuration },
                { "BuildInParallel", "True" } // guessed at this, doesn't seem to have an effect
            };

            var targets = new string[] { target };

            var buildRequestData = new BuildRequestData(projectFileName, globalProperties, "15.0", targets, null);
            BuildManager.DefaultBuildManager.ResetCaches();

            var buildResult = BuildManager.DefaultBuildManager.Build(buildParameters, buildRequestData);
