visual studio 2015 Debug 打断点调试报错解决办法 the breakpoint will not correctly be hit

报错信息：（断点处显示黄色）
The breakpoint will not currently be hit. No symbols have been loaded for this document.

解决办法：
Debug=>Options=>General => Remove the check mark for “Enable Just My Code”
其实就是把"Enable Just My Code"那个勾选去掉就行了。
