When running ASPNetBoilerplate in debug mode, if I have a breakpoint in my controllers, when I access the site from the url, the breakpoint is accessed twice. is there something I might have changed that would cause this.
(breakpoint on HomeController/Index even fires twice).
try with different browser. some browsers resend the request if it fails. so when you wait on the debug line it might be trying to resend the request.
another option; clear breakpoints and write a log to see the behavior.
