Cannot Resolve Symbol 'Page'

Question

After deciding to move everything to Owin , i chose NancyFx to handle my routes, views, etc... however Nancy Razor doesn't seem to work well because i have some weird issues like

1. Cannot Resolve Symbol 'X' .
2. Cannot Resolve Section 'X' .

Here is a picture showing what's going on inside visual studio...

And here is my web.config file

<?xml version="1.0" encoding="utf-8"?>

To set up Nancys flavor of Razor you need a Razor section in your app.config. See https://github.com/NancyFx/Nancy/wiki/Razor-View-Engine for detailed information.
