Can't debug - "The breakpoint will not currently be hit. No symbols have been loaded for this document"

Question

I'm getting the error in the subject line. I'm running vs2k8 on server 2k3sp2. I've tried deleting the pdbs, cache directories, verifying that debugging is set up on the specific page. The interesting thing is other pages debug just fine. Just when I go to this one page. Must be a configuration issue but the page directive looks like this:

print("<%@ Page Language='C#' AutoEventWireup='true' CodeBehind='MemberSearch.aspx.cs' Inherits='SurencyPortal.EmployerPortal.MemberSearch' Debug='true' %>");

I've also noticed that when debugging, if I open the modules window, almost all of the symbols show a status of 'Symbol not loaded'. However, after more research from the msdn article below, one of the MSFT posts said that if it's a core .net dll, it will not load symbols so I'm not worried about that. Some of the microsoft modules (like System.Enterpricesservices.wrapper.dll) show an exclamation point with the message 'the module did not load at the default load address'. Not sure why that dll is there as I don't know of any calls to it.

Here are the thing's i've tried:

Answer 1

The only time I've ever run into an issue like this is if I was trying to debug while the project was in release mode.

Answer 2

I usually see this error pop up when I am working with two separate web 'sites'. I have a web front end and a web service back end. If the development server isn't running for the 'site' the code file is for, then you will receive that error message.

This may not be your problem exactly, however this is usually the situation when I see that error message. Another thing you can do is Debug -> Attach to Process if the debugger isn't attached to the correct process.
