I am using "Microsoft Visual Studio Express 2012 for Web" and I do find immediate window, so it's supported and working fine, I have just checked.
It look like some how you lost your Immediate window in Visual Studio.
You can get it back by using Tools | Customize..
1) Select Commands Tab and Press Reset ALL button OR
2) You can select "Debug | Windows" as Menu bar on the customize dialog and Add Immediate command back. OR
3) You can add it as other menu item, link show in following link:
