Cannot add Scaffold > MVC Controller with views, u

问题:

When I try to add Controller using build-in generator I get following error message:

Where "Brand" is a model class and "ApplicationDbContext" is my data context class.
I never encoutered error like this before. It does not occur all the time (2 success vs 30-40 attempts without changing single line of code). I was able to create Controller for same class minutes ago, but it's really annoying when you try to add something new and try more than 10 times with no results.
Of course, I could write my own controller and views, but I really like using included tools.
I have already repaired VS using "Modify" option in "Add or remove". I'm using latest Microsoft Visual Studio Community (MVSC2015 V14.0.25425.01 Update3).
EDIT:
Brand.cs:

namespace AppBrander.Models  
{  
    public class Brand  
    {  
        public int ID { get; set; }  
        public string Email { get; set; }  
        public string BrandName { get; set; }  
        public string CompanyName { get; set; }  
        public string Description { get; set; }  
    }  
} 

Works in brand new project, fails in old - I guess it's just my VS installation being totally messed up. I should have been guessed, but I just did second repair...
