Visual Studio 2013 IntelliSense stops working for ASP.NET MVC5 Controllers

Question

I am facing a weird problem in my Visual Studio 2013 ASP.NET MVC 5 project. All of a sudden, the IntelliSense in the Controller classes of the MVC 5 project are not working

Answer 1

I get this exact same thing every time I work with one particular MVC5 project. Restarting VS2013 does not work. Deleting suo files does not work. Resetting all tools settings does not work. The only thing that ever works is removing the project from the solution and adding it again. Seeing as I have to do this every day is is really quite annoying. Especially when I have it set to reopen the last files I had open, I then need to track down the ones I was working on and re-open them instead of the popping up automagically..
