调试时出现 'The breakpoint will not currently be hit. No symbols have been loaded for this document' 当前断电不会被命中，符号未被加载的解决方法

stackOverFlow的有效答案：

I had the same problem, I was debugging my project, and i had to right click the project and select "new debug instance". I only needed to do this once, then after that it worked as normal.

方法是：右击项目选择 ： 启动新实例
