Found a solution from this MS article:

MVC 5.1 Tooling Support and Razor IntelliSense are Still Broken Even After Installing VS2013 Update 1 RC

Known issue:

If a VS2013 user installed “Microsoft ASP.NET and Web Tools 2013.1 for Visual Studio 2013” before they install VS2013 Update 1 RC, they won’t be able to get MVC 5.1 tooling support that comes with VS2013 Update 1 RC.

Symptom:

MVC 5.1 tooling support and Razor IntelliSense are still broken even after installing VS2013 Update 1 RC.

Workaround:

1. From "Add/Remove Program", uninstall "Microsoft ASP.NET and Web Tools 2013.1 for Visual Studio 2013"
2. Repair VS2013 RTM
3. Install VS2013 update 1 RC if you have not yet installed it. If you have already installed this, you don’t need to reinstall or repair it.
4. From Web PI, reinstall Microsoft ASP.NET and Web Tools 2013.1 for Visual Studio 2013 or repair Azure SDK 2.2.
