vs 2008 no debugging

my debugging in visual studio 2008 has stopped working , the debugger doesn't hit any breakpoint . what should开发者_运维知识库 i do?

Start by right clicking on the project and rebuilding it. If that works, odds are your project does not have a build definition set up (i.e. you have Debug/x86 in studio, but have not defined this for this project).
