This seems to be happening on a project-by-project basis. Currently I am working on an ASP.NET 4.5 Web Application Project. Intellisense was fine one day but not the next. I am using a custom project template but that should make no difference. I tried editing the text editor settings so that Auto list members and Parameter information are both checked. I tried to reset your Visual Studio settings (Tools --> Import and export settings --> Reset all settings) and I also tried the solution in the accepted answer here:
Has anyone got any insight or suggestions? Pending any answers, I've submitted a Connect bug report: https://connect.microsoft.com/VisualStudio/feedback/details/766891/intellisense-broken-in-vs-2012-rtm

You may be able to refresh Intellisense cache with Ctrl + Shift + R (on standard shortcut keys)
I've had the same issue on VS2010 and fixed it another method described at How to turn IntelliSense on in Visual Studio 2010?
From the link:
Delete the files in this folder: %AppData%\Roaming\Microsoft\VisualStudio\10.0\ReflectedSchemas
(the 10.0 folder may be a different number for VS2012)
If nothing else works, you type this in the Visual Studio Command Prompt (this is in your Start menu) and hit enter: devenv /resetuserdata
This last option is documented here on MSDN, with the following disclaimer:
Disclaimer: you will lose all your environment settings and customizations if you use this switch. It is for this reason that this switch is not officially supported and Microsoft does not advertise this switch to the public (you won't see this switch if you type devenv.exe /? in the command prompt). You should only use this switch as the last resort if you are experiencing an environment problem, and make sure you back up your environment settings by exporting them before using this switch.
