Intellisense partially broken in VS2013 Update 2 RC (Windows Phone 8,1 project)

Hey all.

I'm having a bit of an Intellisense problem. I've attached a screenshot of the code in question (which highlights the broken intellisense, yet the debug info shows that everything is fine).

I've tried resetting my VS settings, deleting the SUO file, and even deleting the Visual Studio folder in my %APPDATA% folder.

The crux of this is, when I create a new solution, these types work just fine - it's just this solution (I've even changed it from a wp 8.0 to 8.1 project, with no luck).

Oh, and the preceding code was

var Hosts = Windows.Networking.Connectivity.NetworkInformation.GetHostNames().ToList();
