在Visual Studio中调试Angular 2使用WebPack慢慢

Question

我正在运行Visual Studio 2015 Update 3，ASP.NET MVC 4.6.1，Angular 2.4.6，WebPack 2.2.1和WebPack Task Runner Explorer Explorer扩展程序。如果我在不调试的情况下运行Visual Studio都可以正常工作，但是如果我尝试以调试模式运行Visual Studio，则需要几分钟才能加载网页。在Visual Studio中查看它正在尝试加载Angular的源地图，并且每个图都需要几秒钟。

似乎问题是因为任务Runner Explorer插件正在运行命令：webpack -d --watch --color，它告诉它始终为所有内容生成源地图。看起来没有一种方法可以更改插件以不运行" -d"开关。在我的配置文件中，我将其配置为仅生成代码的源地图。但是似乎命令行总是覆盖配置文件中的内容。

有人是否可以解决此问题？

问题最终是由于所有供应商和多填充文件造成的源地图太多，而VS的加载时间为太久。一旦我告诉它，它不再为那些开始更快的人生成源地图。
