Ack!

Have you ever selected your folder and said "Exclude from Project" and then if you wanted to add that folder back into your solution, you couldn't. Using "Add existing item" would show you the file dialog and when you select your folder it drills down into that folder. GRR!.

Well there is a better way: 

In your solution explorer window if you select the icon "Show all Files" 

and then "Right click" your hidden folder and select "Include in Project"

Be certain the folder is in the correct file location within your folder structure to see it.
