HttpContext.Current doesn't exist in IIS7 Integrated Mode - asp.net

Question

I just switched from Classic Mode to Integrated Mode and now HttpContext doesn't seem to exist in my ASP.NET application. I can't even add a Watch to HttpContext nor to HttpContext.Current.
I'm using FluorineFX where in the Web.config a HttpModule is defined. Apparently, in IIS7 Integrated Mode, these HttpModules need to be added to the Modules section in System.WebServer. I have done this, but now I'm having this HttpContext problem...
Any idea as why this could happen?
Code is in a simple service class being called by Flex (amf).
if (HttpContext.Current.User.Identity != null)
{
...
Web.Config (I don't know how to display this properly in Stack...):

Answer 1

If you are trying to access it from Application_Start there has been a architectural change that prevents this: IIS 7 Application_Start changes.
AFAIK it should exist everywhere else still.
