Oracle Developer Tools for Visual Studio

say i have a web app that i am running in debug through visual studio, as part of my debug i have put a breakpoint on the oracle stored proc that is being called. how do i get the debugger to stop on that line?

any breakpoints i add always appear with the wee "?" inside them with the tooltip saying

"The breakpoint will not currently be hit. No symbols have been loaded for this document"

how do i load the symbols in order to debug through a stored procedure?
