VS2012未检测到解决方案中的文件夹

Question

I recently had a problem where VS2012 intellisense stopped working in my Workflow dll project. It didn't pick up any of my using classes or created variables. It only opened the intellisense if I used the keyboard shortcut.

Upon creating a new project to test the problem out I discovered that VS2012 didn't detect folders that I created in my solutions now for some reason. (tested it with fresh console app, dll, wf dll).

To fix the intellisense I tried all the recommend things (delete .suo file, clean rebuild, check if setting are enabled, reset settings.) none of them worked. I have no idea what to do for the folder problem or if they are related.

Is there any way to solve this?

The folder problem seems to be solved thanks to @Anton Sizikov. Any idea on the intellisense problem?

Answer 1

It seems that Activities folder is empty, so basically there is no class there, and as a result there is no such namespace defined.

What if you put a class inside it and define a namespace in it?

namespace ActivityLibrary2.Activities
{
   public class Test{}
}
