Project dlls are missing in Modules window

Question

I made a bunch of changes to fix a bug where I could not build. One of those changes finally worked, but now I can't debug!

When I leave a breakpoint in my .cs file, the debugger says:

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

Following the advice of stackoverflow, I checked the modules tab (Debug->Windows->Modlues), to see the symbol load information. The problem is, there is no project.dll!

WebDev.WebHost.dll is there and the included system.dlls are there. I checked my coworker's machine and he has the project.dll, so something that I did broke the debugger.

Things suggested in other article I have tried include:

• Setting the project to debug mode
• cleaning and rebuilding all
• Editing the file and then reverting it to make sure it got rebuilt
• Making sure the correct startup project in the solution properties
• Making sure everything is built in debug mode in the solution properties
• Making sure that the ASP.NET debugger is checked in the project properties
• Making sure that the debug mode was set to full in the project properties
• Disabling 'just my code' in the debugger settings
• Restarting visual studios
• Restarting my computer
• Running Visual Studios as an Administrator
• Checking out a fresh copy of the code from source control
• Upgrading to Visual Studios 2013
• Switching my browser to Internet Explorer
• Making sure IIS is pointing to the right directory.
• Clearing C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\project\ and giving edit permissions to all users.

What sorts of things should I do to get the project.dll into the debugger modules?

May be a bit late to the party but thought I'd share my experience with the exact same problem...

I have a Asp.net Web MVC projcect that I had published to local IIS. After attempting to Attach my visual studio debugger to IIS process I was getting the same 'Breakpoint will not be hit' error, as well as having now project .dll file show in the Debug> Modules list.

My solution was a simple solution in the end but it turns out when I initially published the application to IIS local I had not selected the 'Debug configuration. Because of this I guess my visual studio debugger was never looking for the projects .dll file hence the reason not showing in the list.

I completely removed my app from my local IIS and re-published it using the Debug config rather than Release and it works...
