Application.config "disappears" while debugging Azure WebRole if I pause at a breakpoint for too long

I've noticed this off and on. If I'm locally debugging my Azure WebRole, in Visual Studio 2013, and I pause at a break-point for too long, the current request, or the next one, and all subsequent requests, will result in a 500.19 - Internal Server Error.

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.

Detailed Error Information:

Event viewer says:

The worker process for application pool '902aa9af-0ed8-4126-be43-e533339bdeef' encountered an error 'Cannot read configuration file' trying to read global
module configuration data from file '\\?\C:\Users\<user>\AppData\Local\dftmp\Resources\11468ba0-d99a-45d2-bcce-eae28c7b4e2f\temp\temp\RoleTemp\applicationHost.config', 
line number '0'.  Worker process startup aborted.

And if I go check that directory I see that the file isn't there. I'm guessing the file WAS there at some point, because I was able to make requests prior to that.

Restarting the WebRole seems to fix the problem.

99% of the time this isn't a problem, so I'm sure there isn't actually an error in the config file, it just makes debugging "stressful" since I always feel like I'm under some kind of time limit. :(
