Windows Azure Tools for Microsoft Visual Studio

Hi Experts,
While working on VS I tried to debug my program. But when I tried to debug my program it shows this error.
I am amazed what the problem is and how to make it work?
Thank you.

There was an error attaching the debugger to the role instance ‘deployment17(78) web_IN_0’ with process id: ’8084’. Unable to attach.
