BreakPoints are not working while debugging

Hi Guys,

 

I'm using Visual studio 2015 and working on Web API. When i'm debugging the code ,the breakpoints are not hitting rather than out put is coming.how can i resolve the issue ?.i googled it and found few solutions and tried to fix it.but those solutions are not working for this.

 

Note : If i use the visual studio with just sample console application then the Breakpoints are working .Only for my project (WEB API) it is not working .

 

can u any one suggest on this ?.

 

Thanks and Regards,

Pavan G.
