I have a simple ASP.Net MVC project which for some reason has issues with intellisense. It is constantly giving me errors that namespaces local to the project can not be found, even though they do exist and the project will build fine. Here's an example:

It is very frustrating as this results in me having no intellisense available whatsoever. Has any one encountered a problem like this before, and do they know of a solution?
The project itself is an MVC4 website running in VS2013 in W8 under Paralells on a Macbook Air, should that have any effect on the problem.
As stated, I have no error messages to provide as the project builds and runs successfully, but please let me know if more details are required.
