How do you "re-include" a file that was excluded from source control?

Question

I excluded a file from source control a week ago, and I would like to re-include it into my VS 2010 project.

I can't find a single way to do this, I am completely stumped. I deleted the file, checked everything in, then re-added, checked that in, but I still get the red symbol next to the file saying it is excluded from source control.

Ironically, when I right-click the file, it gives me the option to Exclude it, but not to include again.

Help!

Want to ask a question. How you are adding the file to your project again? With Add an Existing option ?
