Undo VS 'Exclude from project'?

Question

Is there a way to undo the \'exclude from project\' operation in Visual Studio (2008) ?

How to include files back into the project after excluding them?

Answer 1

I couldn't find the "Show All Files" button in Visual Studio 10 when I ran into this problem.

Another way to solve it is to open the containing folder in Windows Explorer by right clicking the folder in Solution Explorer and selecting "Open Folder In Windows Explorer".

Find the folder you want to add back into the project and Drag/Drop it from the Explorer window into your Solution Explorer in Visual Studio.
