debug in release mode

[pdk5]

Hello,

I have a multiple solutions (around 8 solutions ) and each of them have multiple projects.

I am using the incredibuild and built all the solutions in the Release mode.

Now when i try to attach the solution which i want to debug, and try to put the breakpoint in it:
I get error :
"Breakpoint currently will not be hit. No symbols have been loaded for this document"

Not sure what I need to do. I use all the project settings ( which was already there) and since it is huge project, I am bit stuck the moment with this issue.

Forgot to mention, that, I am using Debug -> "Attach to Process" to debug. Because I want to run to some scenario and put breakpoint after that.

Just to let you know (about my expertise level), I am also bit new to visual studio env (eventhough i used c++ with eclipse earlier)

Thanks a lot
Any suggestions will help me a lot
