Question

我当前正在使用Angular 6，.NET Core 2.1，VS2017。在升级到Angular 6之前，我正在使用Angular4。TS文件中的断点工作正常。我已经升级到Angular 6，之后所有TS断点都无法正常工作。

获取有关断点的以下提示。

该断点当前不会被命中。尚未为此文档加载任何符号。

在VS 2017中升级到Angular 6后，TS断点不起作用

这是.NET core 2.1的一个已知问题，开发人员社区中的许多其他社区也报告了该问题：

TS breakpoints not working with ASP.NET Core 2.1

MS开发团队已解决了Visual Studio最新的15.9预览版的问题。您可以从以下URL（https://visualstudio.microsoft.com/vs/preview/）下载最新的预览。

同时，他们建议解决方法是让开发人员在创建新项目时将.NET core SDK 2.0定位为目标，并在项目创建后将项目目标运行时更新为2.1。

希望这会有所帮助。

尝试删除sln文件附近的vs文件夹。还要确保正确设置了调试选项，并且启用了Javascript调试。我对chrome有类似的问题，但在IE中工作正常。在升级vs 2017之后，在运行我的网站时，它询问我是否要启用Java脚本调试。单击“是”后，我可以在chrome中调试。我的猜测是，对于chrome ja调试，必须启用vs中的某些设置
